Lying in the Deep by Diana Urban


A juicy mystery of jealousy, love, and betrayal set on a Semester at Sea-inspired cruise ship, with a diverse cast of delightfully suspicious characters who’ll leave you guessing with every jaw-dropping twist — inspired by Agatha Christie’s Death on the Nile. Coming May 2, 2023 from Penguin Random House!

After being jilted by her ex-boyfriend and best friend, Jade couldn’t be more ready to embark on the adventure of a lifetime—11 countries in 4 months, all from the luxurious Campus on Board ship—and to wedge an entire globe between her and the people who broke her heart.

But when Jade discovers the backstabbing couple are also setting sail, her obsession with them grows and festers, leading to a shocking murder. And as their friends begin to drop like flies, Jade and her new crush must race to clear her name and find the killer they’re trapped at sea with….before anyone else winds up in body bags.

FAQs for Lying in the Deep

No display
What inspired the idea for Lying in the Deep?

Lying in the Deep was inspired by mystery queen Agatha Christie’s Death on the Nile, one of my favorites of hers. You can even say it’s a loose retelling, but, for example, there is no character corresponding to her protagonist Hercule Poirot, and the plot deviates substantially. I also incorporated some tropes I personally adore, such as fake dating and a potentially unreliable narrator. I’ve always wanted to write a murder mystery on a cruise ship, and I had an absolute blast writing this!

When is Lying in the Deep coming out?

Lying in the Deep will be published summer 2023 by Razorbill Books (an imprint of Penguin Random House). More details will be announced soon!

Where can I preorder Lying in the Deep?

What made you want to write thrillers?

Thrillers are my favorite genre! I’ve always relished high-stakes situations, stunning twists, and stories where you feel like you’re piecing together a puzzle right alongside the protagonist. I adore a book that will keep me up way past my bedtime because I simply have to know how it ends. And I love that feeling when the rug is pulled out from under me, but I should have spotted what was coming all along. So I want to write what I love to read! Nothing’s more gratifying than hearing I kept a reader up and turning the pages until 3 a.m., or that I shocked them with a good twist.
