Yours To Keep (The Kowalskis, Book 3) by Shannon Stacey
Can a fake fiance turn into Mr Right? Emma needs a husband, and fast! She's not interested in romance- she's too busy- but Grandma is coming to town, and she'll have non-stop questions about Emma's (stagnant) love life. Sean Kowalski no sooner leaves the army than he's recruited by Emma to be her fake fiance.
He's attracted to the feisty brunette and a little kissing won't hurt anyone- especially when there's no chance he'll fall for a woman settled in a town he's not planning to call home. But when innocent kisses lead to explosive sparks, Emma and Sean discover that their big ruse might just lead to happily ever after...
