Space Opera, read it!

What is the ultimate test of a species' sentience? Is it tool use? The ability to form language? Mourning the dead?

No, the way to test whether a group is sentient is to see if they can create and appreciate art.

Years ago, the various civilizations of the universe decided that the way to keep the peace was to have regular singing/performance contests. Recently discovered species would be "invited" to perform and as long as they did not come in last place, they would be considered sentient and be allowed to live. Those that didn't...

Enter Decebel Jones and the Absolute Zeroes, the has-been glam rock band who will be singing for the survival of all of humanity.

Space Opera blends over the top humor with moving characters and stories. I could not go fifteen minutes without laughing while listening to this book.
