Kidnapped By the Bodyguard by Lena Cove

Aaron Jenkins lives by one rule: never get personal with a client. The former special forces operator turned cowboy bodyguard knows boundaries are what keep you alive—and sane. But when Megan Hill, a sharp-tongued investigative journalist, stumbles into danger chasing the wrong story, she becomes his assignment.
She’s sunshine and sass with a knack for finding trouble. He’s stoic, steady, and far too used to walking away.
From the moment she steps onto his ranch, sparks fly hotter than a Texas summer. Between the secrets, the danger, and one very inconvenient attraction, Aaron’s about to find that protecting Megan means breaking every rule he’s ever made.
