Just This Once is a friends to lovers story between a brilliant prosecutor who's sworn off love and a Navy SEAL who's been hiding his feelings for too long. Becca Hamilton is a busy prosecutor who's dedicated and passionate about her work. After being left high and dry days before her wedding several years ago, she promised herself she wouldn't let her heart become vulnerable again. Yet, she didn't count on temptation in the form of Aidan McNamara.

Aidan McNamara is many a woman's dream - a tall, dark, sexy-as-hell military type who tends to save the day so often it's annoying. Becca has been quite successful at ignoring the spark that burns every time Aidan is near. Until he shows up and happens to save her evening. One scorching hot kiss on a rainy night, and Becca begins to question the limits she set for herself. She gambles she can allow herself just one night with Aidan.

Aidan has been half in love with Becca since the first time he laid eyes on her. A chance encounter kindles hope in his heart. He can't say no when she asks for one night, but he knows from the start he wants more.

Becca quickly discovers that just once won't even come close to satisfying her desire. She's completely unprepared for the depth of feelings Aidan elicits. Forced to take a much-needed break from work, she decides a journey to Last Frontier Lodge in Alaska might give her some perspective and a long overdue adventure. A trip she hoped would clear her head only leaves her missing Aidan so much she can hardly stand it.

Aidan is a man of plans and action, but with Becca, he's winging it every step of the way. When she takes off to Alaska, he finds himself following her even though it goes against his grain. Can Becca let down her guard long enough to let Aidan into her heart?
