After losing her sister and almost losing her father, Calyssa Brentwood is finally returning to a somewhat "normal" life ... until the PKPH virus mutates and attacks, and she once again finds herself scrambling. When her maniacal mother who had been presumed dead resurfaces for a second time, there's far more danger than Lyssa has ever known. But now, when it matters most, she must decide who she should trust and what is truly worth fighting for.
"Riveting, intense, and thought-provoking. Back to Green masterfully weaves the action and tragedy of unregulated science and politics with hope for a better future."
-Mikko Azul, author of The Staff of Fire and Bone
