FAQs for Lying in the Deep

What is Lying in the Deep about?

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.

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!
