Lying in the Deep

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.
