Quick recap
Beaten by the siblings in the last book, Celebrant changes plans. Now he wants the wizenstone, a stone of enormous power kept inside a cursed castle. If the Dragon King gets there first, Wyrmroost can't hold out. Seth and Kendra, the sanctuary's newly appointed caretakers, have to survive an open dragon rebellion, race Celebrant to the castle and convince Wyrmroost's creatures to fight on their side. The mission splits the siblings up and comes at a steep price. The book ends with Seth far from his sister with no memory of who he is, and Bracken missing, which leaves Kendra on her own for the next stage of the war.
