Titans (Kate O'Hearn) Books in Order

If you liked the world of Pegasus and wondered what happened after all that upheaval, Titans is the series that answers it. The books are set fifteen years after the fall of Olympus, when the Olympians have been resettled on Titus and Earth has been declared off limits. That alone gives the series a slightly different feel from Pegasus. The gods are still there, but the story starts from the next generation, with old wars still shaping everyday life.

The main character is Astraea, a Titan who is about to start at Arcadia, a new school meant to bring Titans and Olympians together. She is not convinced it will work. Her best friend is Zephyr, a winged horse, and together they make a great center for the series, especially once they discover Jake, a human boy who should not be on Titus at all. From there, what looks like a school problem turns into a political problem, and then into something much bigger.

That is one of the fun things about this trilogy. It starts with detention, suspicion, and kids from rival groups being forced into the same space. Then it keeps widening. Hidden routes between worlds, old grudges, strange planets, dangerous jungles, and the shapeshifting Mimics all push the story outward. By the time the trilogy is in full swing, Astraea and her friends are not just trying to stay out of trouble, they are trying to stop a war and save captured friends before an entire world falls.

It gets big, fast.

Even so, the series never loses track of its young cast. Astraea is brave, but she is also impatient and unsure. Jake is an outsider in every sense. Tryn and the others bring humor, friction, and loyalty. There is also a nice thread of mistrust slowly turning into cooperation, which matters in a story built on generations of conflict between Titans and Olympians. And because this is a sequel series, readers who know Pegasus will spot deeper connections, including the continued presence of Pegasus himself.

The tone sits somewhere between myth adventure, mystery, and science fantasy. There are gods, winged horses, and ancient grudges, but also schools, rules, and kids having to do what adults failed to do. You can start with Titans on its own, but it lands even better if you have already read the Pegasus books. Either way, this trilogy is best read in order: Titans, The Missing, then The Fallen Queen.
