Summer Donovan is the only person who can save the world from a war that will end it all. If she can figure out who to trust. And who to lie to. And survive long enough to fight her way out of the Underworld. Piece of cake. The war between the Greek and Norse gods rages on with no end in sight. No one is safe from the carnage. Summer and her immortal soulmate Zane have one chance to stop it before the gods clash in a final battle that will destroy the world. Their only hope for peace-and survival-is killing King Lucian, the architect of the war and ruler of the immortals. But taking him out is easier said than done. It turns out that the only weapon that can kill King Lucien is locked in the deadly World of Fire. To get that weapon, Summer needs the help of her not-so-loving father, Hades. And she'll have to outsmart the trickster god, Loki. But Hades and Loki are only a taste of the surprises waiting for her in the Underworld, where nothing is as it seems-and you never know who you can trust. Descend into the EPIC conclusion of the Elementals Academy series by USA Today bestselling author Michelle Madow, a journey through the Underworld filled with twists and surprises that will have you gasping, crying, and turning the pages late into the night.
