Jager by Jessica E. Subject
Jager’s new squad of Defenders has completed training, but the spoiled princess who has grated on his nerves since her first day of training is called back to Hemera for a yearly celebration. When Princess Katrina doesn’t show up, Jager must find her and drag her home, where he wishes she would stay.
Katrina is a Defender, not a princess. And there is no way she wants to return to a planet she hates for some stupid ceremony. Not when she could be out killing Erebus with her squad.
But when a new enemy threatens both their lives, they must work together to survive.
