Titans

by Kate O'Hearn

Published 9 July 2019
A group of kids must stop invaders before they take over Titus—and the rest of the universe—in this first book in a brand-new series from bestselling Pegasus author Kate O’Hearn, who masterfully blends mystery and mythology together.

Fifteen years ago, Olympus was destroyed and the Olympians were resettled on Titus. Since then Earth has been declared a quarantined world. Neither Titans nor Olympians are allowed to visit and under no circumstances are humans allowed on Titus. The Titans and Olympians are keeping the peace. But the deep-seated mistrust still lingers, so when a human ends up on Titus, he could be the spark that reignites the war…

Astraea is a Titan, granddaughter of Hyperion, and now a reluctant student at the brand-new school, Arcadia. She just knows that it’s going to be awful, and that there is no way that Titans and Olympians will ever get along! At least she’s got her best friend, a winged-horse named Zephyr, to keep her company. Then the night before the first day of school, Astraea hears her parents discussing something terrifying: a human has been spotted on Titus. But that’s not possible. All routes to Earth via the Solar Stream have been closed—no one can travel between the two worlds…or can they?

When Astraea and Zephyr get detention on their first day—for fighting with a centaur—they’re sent to the orchards to harvest nectar. There they discover a human boy named Jake. How he got to Titus is a mystery even to him. But Astraea and Zephyr know they have to get Jake home before anyone else discovers him.

But what the trio uncovers is something much bigger than one misplaced human boy. It’s a scheme to take down the rulers of this world, conquer it, and then do the same across the galaxy. Can a group of kids stop the invaders? Or is Titus, like Olympus before it, doomed?

With the weakened Titan prisoners hidden on Earth, Astraea, Zephyr, and their team head to Nesso’s jungle world to seek help in the struggle against the Mimics.

Soon Zephyr and Astraea are seriously wounded. Without ambrosia or nectar to heal them, the group realizes they are in serious trouble. But where can they go for help?

With Zephyr’s life slipping away, Jake and Tryn use their new flying skateboards to try to make it to Xanadu where they hope to find ambrosia for Zephyr and enlist help to join the fight against the Mimics.

Meanwhile, Astraea and the three centaurs must use all their cunning to keep Zephyr safe and alive. But danger comes in many forms, and it seems as though no one may be left to help them—until Jake and Tryn stumble across a lone Olympian everyone believed to be dead…

The Fallen Queen

by Kate O'Hearn

Published 20 July 2021
Astraea, Zephyr, Pegasus, and Tryn turn to an old enemy to save them from a desperate situation in this third book in a new series from bestselling Pegasus author Kate O’Hearn, who masterfully blends mystery and mythology together.

Jake, Nesso, and Emily have been captured by the Mimics. Their friends are determined to rescue them before it’s too late, though that’s easier said than done. Driven from their home and facing a constant stream of new attacks, Astraea, Zephyr, Pegasus, and Tryn are struggling just to survive another day against Mimics who can kill with a touch and take the shape of any friend or family member.

While Jupiter is focused on returning to Titus, Astraea knows their only hope is to take the fight to the Mimic home world and stop the Mimic queen herself. To do that, they’ll need to even the odds of seven friends versus an entire planet. So they come up with a plan to capture the one thing more terrifying than their enemy—the giant snake Lergo.

Seeking out the serpent that almost killed them seems like a terrible idea. But it will take more than one unlikely ally to save their friends—not to mention the universe—and defeat the Mimics for good.
