The Door to the Lost by Jaleigh Johnson
IN THE WORLD OF TALHAVEN, magic is dying. The people of Talhaven had no warning this was going to happen, just as they’d had no warning of the Great Catastrophe. They believed magic was a safe, wondrous force that would always be there to light their homes, fly their skyships, and make their lives easier. They were wrong. The magic that remains in the world is unstable, dangerous—never more so than in the city of Regara, where the Great Catastrophe struck. Now the people of Talhaven fear magic. They have outlawed its use, and blame those who first brought it into their world for all their misfortune.
