Kieran has never had much luck in love or magic. Other than being freed from a family curse that would have killed him and doomed his twin sister, life isn't going his way.

So, after getting put on notice by his boyfriend and accidentally writing a poem so bad (and magically hazardous) that it makes him invisible to the guy, of course Kieran returns home to find the Witches Council sitting in his living room, demanding he complete his magical training. Panicked, he blurts out that his Calling--a kind of magical thesis--will be to find a magical cure-all that can break any curse . . . an enormous task that he absolutely doesn't have the power to pull off.

Nevertheless, Kieran sets off on this dangerous journey, accompanied by his sister Briar, her girlfriend Delilah, and a swoony new crewmate, Sebastian. If he survives, he may just learn how to turn his luck around and figure out what kind of witch, person, and boyfriend he wants to be.
