Book 3 of Emba Oak
 
But treasures lost may still be found, and broken hearts restored. With her devious father back to his full power and Odolf and Fred gone, Emba Oak is at rock bottom. It’s enough to make anyone want to give up and hide. But Emba’s not a giving up kind of girl. If she has to face ghastly ghosts, pirates and a fearsome sea monster to bring Odolf home, then that’s exactly what she’ll do.
