Demigod 12 by Gail Carriger

Puts the opera back into space opera.

Bestselling author Gail Carriger continues her cozy and engaging scifi about the power of art, celebrity, and found family.

Phex and his pantheon have become demigods and are taking their show on a galaxy-wide tour. Phex is shockingly good at singing but his voice is intoxicating and one wrong note can kill so everyone wants a piece of him – sometimes literally. But the aliens in charge of the divinity are hiding something even more sinister and it’s hurting performers and audiences alike. When his lover is pitted against his pantheon, Phex will have to choose between the family he has found and the god he adores.
Let’s take this show on the road – where the show is divine and the road is through the stars. Be careful, the moment you start listening you may never want to stop, and you just might kill to keep the music alive.
