17-year-old Ari Helix is a refugee who has no impulse control. So when she sets off alarms she shouldn’t have on Heritage, a spaceship that belongs to the tyrannical Mercer Company, she and her brother Kay escape from the ship and hide on Old Earth, now a desolate planet. But when Ari pulls Excalibur from a gnarled tree, she unknowingly sets into motion a new cycle of the King Arthur legend. A cycle she doesn’t know has anything to do with her.
