Trevor Finch & The Ghost Ship. Trevor Finch & The Soul Readers, #2

Three friends. Three powers. One messed-up holiday. Trevor is determined to finish Basic Training so he can stop unintentionally blowing things up. But someone is going out of their way to disrupt both his training and his much-deserved beach holiday. Sabotage, poisoning, pirates and a kidnapping. His mysterious foe will do anything to prevent Trevor from becoming a Unique Minds Level 1 Junior Agent - or to win him over to their cause. The family vacation goes from bad to disastrous.
A ghost haunts his dreams at night, and his trainer torments his days. Jay and Kezia are getting on his last nerve, while his bodyguard threatens to ground him forever. His only ally is the ghost who may or may not be working for the enemy. When Trevor is lured onto the infamous Ghost Ship, he faces the most important - and most dangerous - test of his life. The test will reveal his power and the truth about his family.
if he survives. Join Trevor Finch on a pirate ship in a fun, action-packed adventure that's Percy Jackson meets Mission Impossible in Kenya.
