Erin Hale survived what should have been impossible. Once diagnosed with Huntington’s disease, she is now cured—but the mysterious treatment has changed her in ways no one fully understands.

When Erin discovers that her thirteen-year-old niece, Sophie, is suffering from Juvenile Huntington’s disease, she will do anything to save her. With the help of the centuries-old Dr. Direwood, Erin’s mysterious resonance produces an unprecedented result. Sophie survives—but transformed into something entirely new.

Soon, Erin’s healing begins reaching others suffering from Huntington’s disease, drawing desperate patients to her and attracting the attention of a supernatural Council determined to stop her. Erin, Fagen, Sophie, Direwood, and their allies are forced into hiding while they race to develop a safer version of the cure.

But when the treatment successfully cures David—Sophie’s father—it also transforms him, revealing that this miracle comes with a price.

As the Council closes in and Erin’s abilities take an increasing toll, she must discover how to save others without destroying herself.

Darkhorse: The Healing Wars is a supernatural story of love, family, sacrifice, healing, and the dangerous consequences of a miracle the world may not be ready for.
