The formerly glorious god Apollo, cast down to earth in punishment by Zeus, is now an awkward mortal teenager named Lester Papadopoulos. In order to regain his place on Mount Olympus, Lester must restore five Oracles that have gone dark. But he has to achieve this impossible task without having any godly powers and while being duty-bound to a confounding young daughter of Demeter named Meg. Thanks a lot, Dad.

With the help of some demigod friends, Lester managed to survive his first two trials, one at Camp Half-Blood, and one in Indianapolis, where Meg received the Dark Prophecy. The words she uttered while seated on the Throne of Memory revealed that an evil triumvirate of Roman emperors plans to attack Camp Jupiter.

While Leo flies ahead on Festus to warn the Roman camp, Lester and Meg must go through the Labyrinth to find the third emperor—and an Oracle who speaks in word puzzles—somewhere in the American Southwest. There is one glimmer of hope in the gloom-filled prophecy: The cloven guide alone the way does know. They will have a satyr companion, and Meg knows just who to call upon...

In his penultimate adventure, a devastated but determined Apollo travels to Camp Jupiter, where he must learn what it is to be a hero, or die trying.

It's not easy being Apollo, especially when you've been turned into a human and banished from Olympus. On his path to restoring five ancient oracles and reclaiming his godly powers, Apollo (aka Lester Papadopoulos) has faced both triumphs and tragedies.

Now his journey takes him to Camp Jupiter in the San Francisco Bay Area, where the Roman demigods are preparing for a desperate last stand against the evil Triumvirate of Roman emperors. Hazel, Reyna, Frank, Tyson, Ella, and many other old friends will need Apollo's aid to survive the onslaught. Unfortunately, the answer to their salvation lies in the forgotten tomb of a Roman ruler... someone even worse than the emperors Apollo has already faced.

Following their adventures in The Bear and the Nightingale and The Girl in the Tower, Vasya and Morozko return in this stunning conclusion to the bestselling Winternight Trilogy, battling enemies mortal and magical to save both Russias, the seen and the unseen.

Now Moscow has been struck by disaster. Its people are searching for answers—and for someone to blame. Vasya finds herself alone, beset on all sides.

Caught at the center of the conflict is Vasya, who finds the fate of two worlds resting on her shoulders.

Her destiny uncertain, Vasya will uncover surprising truths about herself and her history as she desperately tries to save Russia, Morozko, and the magical world she treasures. But she may not be able to save them all.
