Playing for Keeps by Julie Hammerle

Bryce Barrett has disappeared off the face of the earth. Well, technically she’s just temporarily hiding out in a teeny Midwest town, away from her ruined marriage and professional demise…at least until she can figure out her next steps. But when she bumps into her ex—dressed in what could be only described as “dumpster chic”—she does the only reasonable thing a woman can do: panics and pretends the cute security guard on the scene is her new boyfriend.
Free-spirited nomad Jake Warner knew returning to his hometown was a bad idea. It’s bad enough that his family’s pressuring him to step into his dad’s hypercompetitive shoes and settle down, but when a complete stranger (cute, though possibly unbalanced) enlists him as her fake boyfriend, Jake knows he’s making some questionable choices…especially when he inexplicably goes along with it.
Now these two mismatched misfits are temporary allies against a town filled with happy, normal, and annoyingly stable people. Fake dating keeps everyone off their back while they plot their respective escapes. But nothing botches a plan more than unexpected chemistry…
