The Witches of Calamora — Edita A. Petrick

Kitaya has four hundred and forty three mothers. She lives inside a forever-changing messy yard protected by a massive wall. She's home-schooled and when her mothers take her on a field trip, it's usually across the galaxy to learn how stars are born. She calls her home the Calamora Fort. Her friend, Joshua, calls it prison. What the jungle tribes call it depends on whether the frontier gods allow them to see it. When the Witches begin erasing Joshua's memories, Kitaya knows they mean to send him away. At thirteen her magic isn't strong enough to defy the tribe of self-styled gods, but there's an option: steal Joshua's dormant body and run. She's determined to reach the human party moving through the jungle and is so focused on her goal ahead that she forgets to look behind. By the time she does, death and destruction are not just close but have caught up.
