Truth or Spare by K. Sterling

Split happens.
Too cynical to pin his hopes on a miracle, Dewey “Doobie” Brooks has his doubts when a charming stranger arrives in Oslo, New York, looking for a job and a place to stay. Running the family bowling alley, raising his brother’s son, and hiding an autoimmune disorder have left him in need of help—but finding a capable, reliable adult in his small town has been hopeless.
Theo von Hessen is neither capable nor reliable. An Austrian prince and philanthropist with a reputation for being an unrepentant playboy, he has never held a real job and is clueless about manual labor. But the moment he sees a “help wanted” sign and Oslo’s tired town hero, Theo’s convinced fate sent him there to make a difference.
It isn’t all fun and games at Brooks Family Bowling. Dewey is at his wits’ end and doesn’t know what to make of his new employee. Is Theo on the run, or is this some reality-show stunt? Neither can deny their attraction and romance strikes, but will Theo wind up in the gutter when his true identity is revealed—or has he finally found his purpose and a chance to rewrite his own story?
