29-year-old Paul Donnelly has been many things in his life. Son of addicts, high school dropout, tattooist, the shameless bodyguard to Beckett Cobalt, the "bodyguard camp counselor" to the rookies of SFO, Loren Hale's nemesis, and Xander's wise one.

But nothing means as much without Luna Hale. The sci-fi-loving writer. A weirdo. Sister to his client. The only one he's fallen for.

To be with Luna, he has to ensure it's totally, completely, unmistakably safe. That starts with taking care of his family—the family he walked away from as a teenager.

He knows he'll survive. He can survive anything. But this time, he just wants to survive with her.

Take an epic cosmic journey with Luna & Donnelly through heartache, hope, darkness, love, and an unceasing light—where the bonds we make are what power us through time.
