Emil and Brighton defied the odds. They beat the Blood Casters and escaped with their lives or so they thought. When Brighton drank the Reaper's Blood, he believed it would make him invincible, but instead the potion is killing him. In Emil's race to find an antidote that will not only save his brother but also rid him of his own unwanted phoenix powers, he will have to dig deep into the very past lives he's trying to outrun. Though he needs the help of the Spell Walkers now more than ever, their ranks are fracturing, with Maribelle's thirst for revenge sending her down a dangerous path.
