   Summary

   Grace has almost everything he ever wanted— his brother back, great friends, a roomate he likes maybe a little too much, and now a summer job as an alien life expert on Jody's second space opera film.

    

   The problem? Tom Ryder, who refuses to get over their fling from years ago and takes any and every opportunity to flirt with him and earn his second chance, though Grace has gone through great lengths to keep the whole situation off of Colt's radar. 

    

   The solution? Definitely not a fake boyfriend, and absolutely not a fake relationship with the man he shares a home with. He really, really shouldn't lie to everyone around him, but Ryder's ego is easily bruised, and he won't destroy Colt's career, too. Oh, and he's a cat smuggler now, apparently. 

    

   “Oh yeah?” Ryder asks, narrowing his eyes almost comically. “What’s his name?”

    

   "Simon." 

    

   Hey, brain, what the heck was that?!
