Lainey and Silas show up on the study abroad cruise ship with Jade. Lainey was her best friend until she stole her boyfriend Silas away from her and broke all connections to her. Jade starts faking a relationship with someone named Felix she meets on the ship to make the new couple jealous. Then Lainey ends up murdered and thrown overboard. Lainey's dad owns a big pharmaceutical company that has been up to sketchy things and there are many people on the ship tat have a grudge against the company. Could they also be there to murder Lainey? So many possibilities on who did it. At first I thought I had it all figured out and was bored thinking this is so obvious but boy was I wrong. Never would have guessed what really happened.Lots of twists and turns towards the end. Kept me interested and invested the whole time. Overall a good book. Very easy and fast read.
