Until Then by Emily C. Childs

Noah Hayden, star of the hottest TV show, is convinced it’s impossible to know who’s dating him for him and who’s out for clout.

Until he collides with a beautiful stranger named Hayley and what began as a battle over the last coffee shop scone turns into the perfect day and perfect night together. Just as Noah thinks he might’ve found the elusive “one”, Hayley ghosts him without an explanation.
Months later, their paths cross again at a mutual friend’s Hollywood wedding. Noah plans to avoid Hayley, until her cheating ex corners her and before he can think twice, Noah has her in his arms, blurting out they’ve been ridiculously in love for months.
After a rogue paparazzi catches a photo, Noah and Hayley decide to fall into the ruse temporarily. Of course it will be mutually beneficial–he escapes the gold-diggers and she earns new limelight on her financially struggling therapeutic horse ranch.
But when their fake relationship brings up unspoken feelings and unearths new truths of the future, Noah has no idea if he’s going to lose her again, or if his impulsive plan will lead to something so much more.
