Falling Fast by Caroline Lee

Once upon a time, two people met and fell in love at River’s End Ranch. Nothing unusual there—this is at least the sixtieth couple the ranch has brought together! But unlike those other Loves, this one ended in disaster.
It’s been three years, and Faith Kalani is like 92% certain she’s over her broken heart. Sure, her professional skiing dreams ended with a broken leg, but she’s happy being back here at River’s End Ranch, giving ski lessons… Right up until she offers to take over a colleague’s snowboarding lesson, and she gets a good look at her new student.
Patrick Quinn broke Faith’s heart three years ago, and has never forgiven himself. But when he sees the incredulous look on his snowboarding instructor’s gorgeous face, he knows he’s been handed a second chance. Despite their awkwardness, the two of them are good together…too good, maybe. Faith can’t decide if she loves or hates that reminder, but when Patrick is badly injured during his first lesson on the slopes, she knows she’s the one who needs to step up and take care of him.
Forced into close proximity, she finds herself falling fast for the man who once held her heart. But how can she possibly trust him again, after what he did? With the Founder’s Day Gala approaching, Valentine’s Day right around the corner, and a Leap Day birthday, Faith doesn’t have time to figure out her feelings.
But maybe all this couple needs is a little bit of that River’s End Ranch magic!
