Lying in the Deep by Diana Urban
My rating: 3 of 5 stars
The Gist
When I picked up Lying in the Deep, I was ready to be hooked. A semester-at-sea program. A murder on board. An isolated cruise ship full of secrets. That setup should’ve practically written itself into a suspenseful, claustrophobic thriller. And for a while, it really seemed like it would.
But once I got past the first few chapters, it became clear that this book wasn’t going to lean into the eerie, locked-room mystery I expected. Instead, it swerved into full-blown teenage drama — complete with jealousy, romantic angst, and more irrational decision-making than I had patience for.
The Details
Our protagonist, Jade, boards the cruise with one goal: escape the heartbreak of betrayal. Her ex-boyfriend and ex-best friend are now dating — and just so happen to be on the same boat. That tension could’ve added a juicy emotional layer to the story. But it completely hijacks the narrative.
Rather than focusing on the murder mystery or the looming sense of isolation, the plot becomes bogged down in emotional outbursts and hormonal chaos. Jade jumps to conclusions constantly. She assumes the worst in every situation, always convinced that she’s at the center of every motive and secret. I get that she’s a teenager — but her lack of self-awareness and extreme reactions made it hard to sympathize with her.
The love triangle drama takes up way too much space. Conversations that should be tense or revealing often devolve into back-and-forths about who kissed whom, who lied, and who still has feelings. Meanwhile, the actual mystery? It lingers in the background, underdeveloped and often brushed aside.
The pacing also struggles. Key events are skimmed over or happen off the page. There’s very little buildup to the major plot twists. At times, I felt like entire scenes were missing — especially the ones that could’ve shown how dangerous, tense, or atmospheric the ship really was. The setting had so much potential, but it felt wasted.
I wanted to feel that trapped-on-a-boat claustrophobia. I wanted to second-guess everyone’s motives, to question every smile and side-glance. But instead, I spent most of the book watching Jade spiral into emotional breakdowns over a boy. The danger never felt real. The urgency never landed.
That said, Urban’s writing is accessible and fast-paced. The book is easy to fly through, and I can see why some readers might find the drama addictive. There are moments of tension and some brief flashes of clever misdirection. If the focus had shifted more toward the mystery and less toward the love story, I think it would’ve landed much better.
The Verdict
In the end, this is one of those books that had all the ingredients — but didn’t mix them in the right order. It’s not a total loss, but it never fully delivers on its promise. For readers who enjoy messy teen relationships with a side of suspense, this might work. But if you’re in it for the thrills, the mystery, and the setting? You’ll probably find yourself skimming ahead and wishing the story went deeper.
