The Bodyguard by Katherine Center

She’s got his back.
Hannah Brooks looks more like a kindergarten teacher than somebody who could kill you with a wine bottle opener. Or a ballpoint pen. Or a dinner napkin. But the truth is, she’s an Executive Protection Agent (aka "bodyguard"), and she just got hired to protect superstar actor Jack Stapleton from his middle-aged, corgi-breeding stalker.

He’s got her heart.
Jack Stapleton’s a household name―captured by paparazzi on beaches the world over, famous for, among other things, rising out of the waves in all manner of clingy board shorts and glistening like a Roman deity. But a few years back, in the wake of a family tragedy, he dropped from the public eye and went off the grid.

They’ve got a secret.
When Jack’s mom gets sick, he goes home to the family’s Texas ranch to help out. Only one catch: He doesn’t want his family to know about his stalker. Or the bodyguard thing. And so Hannah―against her will and her better judgment―finds herself pretending to be Jack’s girlfriend as a cover. Even though her ex, says no one will believe it.
