Wild Nights with a Lone Wolf by Elisabeth Staab

(Lone Wolf, Book 1) Agent Sherri Walker needs a change of scenery. Her former lover nearly tanked her career, forcing her to take a leave of absence. A few drinks and a one-night stand with a sinfully hot stranger look like a great way to take her mind off her troubles, until that stranger’s past lands her in a new world of danger. Asher Hughes left his outlaw pack but couldn’t ditch the bad blood. A lone wolf who’s always refused to bond, Ash is left wanting more after one night with a beautiful, spirited human. Worse, it puts Sherri in the crosshairs of an old pack enemy, and the only way to save her is to claim her as his own.
