High Tide — Jill Sanders

Grace was trying to escape being left at the altar by her best friend since grade school. The fact that Corey had ditched her for some bimbo he'd met during his bachelor party wasn't even the worst thing that had happened to her. No, the worst part was that she'd gone on her honeymoon, alone, had a one-night stand with a sexy bartender and nine months later ended up with the surprise of her life. 

Alan was right where he wanted to be. In the thick of single-hood. He loved his job as a bartender at The Boardwalk Bar and Grill, finally had money to spare, enjoyed spending his days on the Gulf and his nights with a new lady. Life was great. That is until Grace returns. He'd had a fling with her over a year ago and had fallen hard and fast for the blonde until she'd left to return home and had taken the last shred of hope for a better life with her.
