Apparently, Sir Cameron Needs to Die,

In this hilarious, off-the-wall queer fantasy romance, a reclusive sorcerer is forced to protect a cowardly knight after a prophecy ties their fates together. Funny, touching and inventive, this book is perfect for fans of A Marvellous Light and Dreadful. All his life, Sir Cameron has tried to stay as far away from danger as possible. But when the Church hands down a prophecy to his fellow knights predicting that the only way to defeat their nemesis, the mad sorcerer Merulo, is to kill Sir Cameron, he finds himself in a situation too sticky for even his considerable wiles. Short of ideas, Cameron throws himself on the mercy of the one person who now actually wants him to survive: the mad sorcerer. Merulo isn't thrilled to be babysitting a spoilt, attention-seeking knight, but fate has tied them together. And transmogrifying Cameron into a vulture is at least a great source of entertainment. Cameron, meanwhile, is on a voyage of self-discovery. It turns out he's really, really into surly sorcerers who lock him up and tell him what to do. Who knew? As a legion of knights surround their stronghold, led by an angry concussed elf—which definitely isn't in any way Cameron's fault—the sorcerer's poisonous ambitions draw ever closer to fruition. Cameron is quite invested in not dying, but he finds he's also invested in Merulo. And sometimes, supporting the sorcerer you care about means taking an interest in their hobbies. Even if their hobby is trying to kill God. Even if it might get you killed, too.
