Simon expected more from life than being orphaned in ancient Greece and stuck in the Underworld for eternity. Determined not to forget who he is, he commits himself to escaping Hades. Along the way, he faces the monster Cerberus, befriends the tormented Sisyphus, and becomes Persephone’s favorite servant. Then, after centuries of failed attempts, he is finally thrust into modern times—and into the stall of a middle school bathroom. Naked.
With the help of Zeke, a nerdy rich kid on the social fringes, Simon learns to navigate this amazing and bewildering world. And with Simon’s help, Zeke begins to question his comfortable life and understand the true meaning of friendship. Everything seems to be going great . . . until the god of the Underworld sends a demon girl to bring Simon back. And suddenly, it’s not just the secret of Simon’s past that’s threatened, but their very lives—and everyone’s around them, too. Is their friendship strong enough to withstand the Will of Hades and save St. Nikolaos Academy Middle School?

When young Heidi is sent to live with her grandfather in a small shepherd’s hut in the Swiss Alps, everyone expects him to turn her away.

A turtle the size of an island. A cricket that can possess you if swallowed. A giant who turns enemies to stone. The legends of Southeast Asia—or “the lands below the winds,” as explorers used to call it—are populated with a whole menagerie of colorful beasts that inspire awe and fear in equal measure. Yet, passed on as they are through story and song, so many of these stories remain rooted in some long-forgotten past and bound by the borders of the region, creatures of myth and memory and nothing more. Until now.
