Through a series of flashbacks, we're introduced to Tamsin's teenaged backstory at Valkyrie school under the tutelage of Freya and later Acacia. The plan to return Hades to Tartarus is complicated by the fact that his desire to assemble an army is now out in the open. Will Tamsin lead the armies of Hell? What is Jack really up to? Will Dr. Lewis eventually be able to return Evony to her greatness as The Morrigan?
