Lady of Shadows by Breanna Teintze

Outlaw wizard Corcoran Gray expected death to be final, but life, and his loved ones, had other plans. A year after being resurrected and flung into a new body, he’s still trying to come to terms with his situation – and his self – when the all-powerful Mages’ Guild demands his help to stop a deadly plague.

He’s inclined to refuse the organisation that still wants him dead, until his partner Brix starts showing symptoms – to save her, Gray will do anything, even if it means working with his greatest enemies.

But it quickly becomes clear that this is no normal plague. The situation is more complicated, and more lethal, than anyone has realised. Ancient dangers are stirring, and thousands of lives are at stake . . .
