Yara has spent the last three years in Brazil, diligently studying with Vovó to develop her Waker abilities and desperately searching for a cure for Brent. Though her powers—and her control over them—have grown, every possible cure for Brent fails. And they're running out of the only medicine that keeps him alive.
When a letter from the American Wakers recalls Yara and Vovó to California, Yara has to weigh the fading chance of saving Brent against the dangers of placing them all within the grasp of an old enemy. Not only has his power grown, but the barrier between our world and the spirit world is becoming dangerously thin. As the threat to the Wakers increases, Yara doesn't know if she'll be strong enough to defeat him.
Her only hope is to put her trust in some unexpected allies and fully embrace her Waker heritage. If she fails, not only could Brent die, but the power of the Wakers could disappear forever.
