The Curse Breaker (Isle of Ever, Book 2) by: Jen Calonita

The game is far from over. In fact, it's only just begun.

Having finally reached the Isle of Ever, Everly "Benny" Benedict thinks she's won the game of clues her ancestor Evelyn Terry set out for her in her will. Only she can't prove it yet―not until her new friends are safe from the curse that has kept them trapped for centuries!

And now there's a new game. It turns out that Evelyn has more secrets in her diary and another task for Benny: to find the lost piece of pirate treasure needed to break the curse once and for all. It won't be easy. One of her best friends has betrayed her; the kids from the island are just discovering twenty-first- century life, and a mysterious stranger mentioned in Evelyn's diary has somehow turned up in present-day Greenport.

Benny has to figure it all out in just a few days. If time runs out, someone else can claim the inheritance, and the Isle of Ever will disappear again for another two hundred years!
