The suspenseful third installment in The Underland Chronicles by Suzanne Collins, New York Times bestselling author of The Hunger Games!

With two prophecies fulfilled, Gregor is now focused on the Prophecy of Blood, which calls for Gregor and "the princess," Boots, to return to the Underland to help ward off a plague. His mom agrees to let them go -- on the condition that she travels with them.

When they arrive in the subterranean city, the plague is spreading -- and one of Gregor's family is stricken. Only then does he understand his role in the prophecy. He must summon all his power to end the biological warfare, or the warmblood creatures of the Underland will die.
