Cursebreakers by Madeleine Nakamura

Adrien Desfourneaux, professor of magic, must survive his own failing mental health and a tenuous partnership with a dangerous ally in order to save the city of Astrum from a spreading curse.

Adrien Desfourneaux, professor of magic and disgraced ex-physician, has discovered a conspiracy. Someone is inflicting magical comas on the inhabitants of the massive city of Astrum, and no one knows how or why. Caught between a faction of scheming magical academics and an explosive schism in the ranks of the Astrum’s power-hungry military, Adrien is swallowed by the growing chaos. Alongside Gennady, an unruly, damaged young soldier, and Malise, a brilliant healer and Adrien’s best friend, Adrien searches for a way to stop the spreading curse before the city implodes. He must survive his own bipolar disorder, his self-destructive tendencies, and his entanglement with the man who doesn’t love him back.
