“I absolutely love this! Couldn't stop listening, finished in one go.
From the beginning it have me captivated, from the amazing narration, to the heart stopping, weep inducing story. It had my brain going from start to finish trying to figure out the who, but mainly the why... Love that even when you get who it was, it still had your brain engaged and thinking.
The way you get attached to every character, wishing for things to end different, just because you want everyone to have their happy ending. It is a proof of how great every character is written that you are cheering for the "bad guy".★★★★★

The DeMondego Diamond by Greta Craig is a ⭐⭐⭐⭐⭐ graphic audio series 💚💎🎧
Action starts when six college friends reunite at a wedding - eight years after one was convicted of murdering another. 😨 The dual timeline of this dark academia mystery jumps from a college campus in the American South to the wedding day on the DeMondego estate 8 years later. 🕰️
This story will make you question where do your sympathies lie - with the bubbly star of the show or her convicted murderer. 🤐
I genuinly devoured this audio. 🫠 Production quality is out of this world, VAs' work pulled me in even deeper into the story and I was finished before even realising. 💖”★★★★★

“I did not expect to love this as much as I did.
The DeMondego Diamond gave me exactly what I want from a murder mystery: enough information to actually investigate alongside the story. I could catch clues, build theories, change suspects, get some things right, get other things very wrong, and then watch all of those seemingly small details click into place.
And the best part? It played fair.
There were multiple moments where I noticed something that seemed oddly specific, filed it away, and later discovered that YES—it mattered. That made solving pieces of the mystery incredibly satisfying without making the larger mystery predictable.
There is a LOT happening here: two timelines, an old murder, a present-day murder, a complicated conviction, a diamond, years of secrets, and one spectacularly messy group of former college friends. Somehow, none of it felt chaotic. The past timeline continually gave new context to the present, and the complicated romantic dynamics weren’t just drama thrown on top—they affected loyalties, motives, grief, secrets, and how everyone remembered what happened.
Jasper was probably my favorite character, but honestly, this worked because everything worked together.
And then there’s the audiobook.
Full cast. Cinematic sound design. Eleven credited performers. This could have been an auditory hostage situation. 😂 Instead? 10/10. No notes. Give me more.
The production added atmosphere without overwhelming the story, the characters remained easy to distinguish, and even the episode structure contributed to the feeling that I was listening to something cinematic rather than a traditional audiobook.
I also really appreciated the content warnings provided before individual episodes. There are some heavier subjects throughout this story, and rather than trying to create my own incomplete list here, I’d recommend listening to those episode-specific warnings as you go.
And the ending?
Perfect for this story.
Will every reader agree with me? Probably not. Do I care? Nope. 😂 It landed exactly the way I wanted it to.
This wasn’t just a mystery that surprised me. It let me play. And that is so much more fun.”

“This is easily one of the best audiobook experiences I’ve ever had, and probably my favourite narrator ever! Her voice is so soft and suits the story perfectly, and the way she reads it almost sounds like poetry. All of the actors were amazing, and the whole thing genuinely felt like I was listening to or watching a movie. I’m a fan!
The production is incredible, you can tell this was written specifically to be an audiobook experience. The added sound effects make it so immersive, and the writing is beautiful and perfectly descriptive. It was addictive from the start, and I was recommending it within 15 minutes!
The story itself was a little predictable for me, but honestly, I didn’t care. The production and overall experience were that good. This is easily in my top two audiobooks I’ve ever listened to, and the fact that it was essentially a one-woman show makes it even more impressive.”★★★★★

“This fabulous mystery has it all-obsession, suspense, murder, intrigue, found family, friendship, a dual timeline-in a dark academia setting. The story revolves around six friends in college. Beau, Ben and Daisy have known each other since childhood. Daisy and Caroline are roommates and then Nora joins them. Ben, Beau and Jasper share the upstairs portion of the same house. Ben and Nora are dating. Beau and Caroline are “seeing each other”. Feelings are convoluted here-unrequited crushes, obsession. After a party one weekend, Daisy falls from the clock tower in town. Was it an accident or murder? Who is guilty? Who’s convicted? Will we ever know the truth? Fast forward eight years to a wedding and answers.
The duet multicast performance was beyond extraordinary. Dave Greggs was fantastic as charming, somewhat arrogant/entitled Beau. Sophie Terry was magnificent as sweet, kind, lonely, determined Nora. Michael Brigant was superb as compassionate, sweet, loving Ben. Sophia Radford was spectacular as friendly, naive Daisy. Her Southern accent was perfect. Isaac Trenton was delightful as considerate law student Jasper. Cindy Xu was terrific as entitled, unhappy, jealous Caroline. Sean Finnerty was perfect as Eben Wisp-Beau’s curious relative. Casey James was splendid as Ms. Beaufort-Southern accent and all. Lucius Po was amazing as the policeman and Nora’s father. Millie Telman was absolutely brilliant as young Daisy. Greta Craig-marvellous writer, director, producer, sound designer, mixer and general narrator for the series. I highly recommend listening to this audiobook.
AUDIOBOOK REVIEW: Story 5 stars Narration 5 stars”★★★★★

“This audiobook was SO incredibly fun!! as the resident true crime podcast lover in almost every single friend group ive ever had, this audiobook felt like i was sitting down ready to lock into a huge youtube series about a true crime case!
this is separated so you could listen to each chapter as a podcast episode but honestly i was so sucked into the story that i couldnt help but binge it from start to end in one sitting... this is the definition of messy drama between uni kids turning fatal and really goes to know what some people will really do for love and acceptance.
i will say i did guess the plot twist but it honestly didnt take away the excitement of listening to this audiobook at all - i was truly sat and HAD to listen to every word with bated breath still!
now if anyone is like me and generally cant agree with graphic audios because they speed up their audiobooks and everything ends up being too messy, i can confirm that this one doesnt fall victim to that at all! there was so many fun additions to this over the narration like background sounds (like chattering from groups of people, birdsong and wind outside etc.) and it made everything so gripping! and the narrators??? truly a work of art - everyone had their role and was so locked in that i truly believed every word everyone was saying.
I can say with confidence that I will be checking out this authors future works and the narrators! everything was incredible <3”★★★★★

“The DeMondego Diamond: A Murder Mystery follows 6 college friends who are haunted by the ghost of their past as a result of losing one of their beloved friends and the “golden girl” of the group. At first you believe that she is this perfect friend, in the perfect friendship group, but as the story goes on you learn that there are many issues within group, resulting in toxic relationships, untold secrets, forbidden love, and profound longing and yearning.
The story follows a dual timeline in the present and the past, with multiple POVs and a narrator. The author has produced a story with a very lyrical style using the tools of rhythm, musicality, vivid imagery, and emotional resonance, which is captured perfectly by each voice actor. The story leans into Romanticism, especially through characters who choose feeling over logic. The cinematic background audio adds a beautiful layer to the story, adding to the whole overall experience. I recommend wearing your headphones for the most immersive experience.
I absolutely adored listening to this dark academia, murder mystery. It is hauntingly beautiful, and perfect in every way. A 5 star listening experience. I am so glad I requested the ALC as it provoked so many emotions and I genuinely wish I could listen to this again for the first time. There are so many plot twists in this story that I was hooked from episode 1 right through to the end!”★★★★★

“The DeMondego Diamond had me hooked from the start. I loved how the full cast made it feel more like a TV show than an audiobook. Every voice actor brought so much emotion to their character, making the story feel incredibly real. The story flowed smoothly between the past and present, and I never wanted to stop listening. If you enjoy immersive audiobooks with fantastic performances and an addictive story, I definitely recommend this one!”
