Somebody wanted Minerva Rus dead. They succeeded. But Minerva isn’t letting a little thing like death stop her. After the dangerous adventure that killed her in Memortality, Minerva Rus has reconciled herself to being dead. She and her also-dead boyfriend Raven share an amazing gift that allows them to bring the dead back to life—including each other. Now that Jules, their most dangerous enemy, has been banished from reality and trapped inside her own mind, Minerva and Raven plan on enjoying the eternity of their unnatural lives.

But immortality isn’t safe. Minerva and Raven’s life-giving powers mysteriously fade, forcing them to take refuge in The Between, a shadowy realm of memories that lies between life and death. What's more, their old adversary Jules is on the loose, partnered with a resurrected Nazi scientist planning a monstrous experiment that will change the destiny of the human race. And now it's up to a 21-year-old dead girl to save the world—again.
