“A powerful cast of characters in an epic tale of dragons and magic.” —Lisa McMann, New York Times bestselling author of The Unwanteds

Follow the threads of the Fates to the captivating conclusion of this timeless fantasy series about four unlikely heroes bound together to save their world—and magic itself.

Since the moment Wren, River, Blue, and Shenli learned that they are the four heroes fated to save their world, each has been grappling in their own way with that sense of responsibility. Now the stakes have been raised like never before.

River's new mage powers are dangerously uncontrolled, posing a threat to anyone who comes near her. Only one person holds the key to helping River master her abilities before it yields dire consequences. Shenli must finally confront the impossible decision of whether or not to betray his own sense of right and wrong in order to save an entire lost people. And Wren and Blue set out on the difficult task of opening the closed minds of the people of Gerbera to gain their assistance before it's too late.

As the four friends strive to live up to their prophecied roles, none of them know that there is someone else out there who believes her sole destiny is to stop the heroes--whatever it takes.
