His Strings to Pull by Cathryn Fox

A whirlwind affair…or a headlong plunge into the deep end of forever?

As lifeguard Jenny Anderson keeps one eye on the rambunctious kids at the community pool, she can’t help but keep the other one trained on the gorgeous, tattooed hottie peeling his shirt off near the lounge chairs. And she isn’t the only woman at the pool drooling.
Right about the time her gaze drops to check for a wedding ring—which, from bitter experience, she knows doesn’t mean squat—one of those kids plows into her from behind. Sending her in an ungraceful belly flop right into the deep end.

When the sleekly tanned lifeguard literally falls into his arms, her mouth opening and closing like a landed fish, Ving Duncan’s special forces training kicks in. It’s clear she needs air, and she needs it now.
The moment their lips collide, he wants her, all strings attached. By the time he finds out who she is—his comrade’s little sister—it’s too late. He’s hooked, and he’s already planning his next mission: to get her to say yes. To a date. Maybe to forever…
