Lying in the Deep is a delicious and lush mystery filled with intrigue surrounding Jade on her Semester at Sea trip to 11 countries in 4 months. What she doesn't expect is to be joined by her recent ex-boyfriend and ex-best friend who have begun dating after breaking her heart. When Jade can't seem to avoid the pair, her former friend accuses her of stalking them and then a shocking murder interrupts the trip. As friends and classmates being to be murdered, it's up to Jade and her friends to put together the pieces and unmask a murderer, lest they be next. This book was shocking and thrilling full of backstabbing, jealousy, and suspicion. It held my attention until it's jaw-dropping conclusion and I loved the story. The characters were well flushed out and intricately written with good motives and drives. There were many twists and turns that leave you guessing right up until the end!
