Song of the Stars

An alien prince who gave up everything to save his people. A young janitor who just wants to get home to his family. An intergalactic threat that could destroy both them and our world. A century ago Prince Belenos was offered an impossible choice: struggle through losing battle after losing battle while his people are decimated, or sacrifice his entire existence to become a powerful symbiotic weapon.
But absolute power corrupts, and Belenos's host is no exception. Forced to sever a lifetime bond to stop his host's cruel reign, Belenos is left crippled and banished, with only the songs of the stars to keep him company. Isaac Anderson is content to work nights as a janitor to support his wife and young daughter, but an unexpected attack on the research facility he cleans makes him a reluctant hero instead.
Someone is collecting space weapons, and Belenos is at the top of their list. Bonding with Belenos could destroy the peaceful life he's built, but rejecting him could leave the whole galaxy open to a bigger threat than even he realizes. Together, Belenos and Isaac could become an unstoppable protector, or they could become more dangerous than the destructive force they are trying to stop. The songs of the stars that helped Belenos can keep them on the right path.
If only they listen.
