When Lauren Walker's relationship with her boyfriend, Spencer, falls apart, the last thing she expects is an offer from his former boss—billionaire hotel mogul Jason Winters.

With his family's business on the line and mounting pressure to prove he's worthy of running the Winters empire, Jason needs the perfect fake girlfriend. Lauren needs a fresh start. Their arrangement seems simple enough... until pretending becomes far more complicated than either of them anticipated.

From glamorous hotels and private plans to unexpected challenges and buried secrets, Lauren and Jason find themselves drawn together in ways neither of them planned. As the lines between pretense and reality begin to blur, they'll have to decide whether risking their hearts is worth the chance at a love neither of them saw coming.

A Billion Reasons Why is a heartwarming, kisses-only, fake-dating romance filled with sparkling chemistry, emotional depth, and the reminder that sometimes the best love stories begin with the most unexpected arrangement.
