The Valentine Wager by Nan Reinhardt

He’s a notorious flirt, so she lays down a challenge she’s sure she’ll win.

When playboy police lieutenant Ryker Lange stops Kitt Boynton for driving on the wrong side of the road, his attraction to the feisty Irish lass is immediate. Yet, despite the sizzling chemistry between them, Kitt quickly turns him down.
Kitt has moved to River’s Edge for a fresh start and is ready to focus on her new marketing job at her cousins’ winery. She’s done with players, and vows she won’t let the local sexy cop distract her, but Kitt, a flirt herself, is definitely tempted. To keep her sanity as she prepares for several Valentine-themed winery events, she and Ryker make a bet: for the next three weeks, neither of them can flirt with the other.
The game starts out lighthearted, but when the town takes sides, Ryker and Kitt must choose between winning a wager or finding lasting love.
