Secretly Hers (Sterling Canyon #2) by Jamie Beck

On her thirty-first birthday, hopeless romantic Kelsey Callihan has all but given up on happily ever afters, which is why she agrees to a risqué proposition from Sterling Canyon’s notorious playboy, backcountry skier Trip Lexington. After all, every girl needs a little fun, and with Trip, there are no mixed signals or risks of a broken heart. And if his tips can help her land a husband in the process, all the better.

Trip couldn’t be happier with his secret, no-strings fling with sweet and sexy Kelsey until she calls it quits after meeting a man she believes could share her dream of marriage and family. His jealousy turns to outrage when he discovers that the man is his estranged half brother and lifelong rival.

Now Trip must decide whether the fire in his gut is due to sibling rivalry or something much more dangerous…like love.
