Estie Williams is a moderately successful romance novelist with a well-managed mood disorder, but lately she'd trade her hard-won stability for just a spark of inspiration. James Heron has been told by students and coworkers alike that he's Blue Sky Resort's most uptight ski instructor, and he's at a loss as for how to loosen up without losing his sobriety. Lightning strikes when the two are thrown together after Estie's considerably more athletic family abandon her to ski school while on vacation in Montana. Together, can Estie and James learn to navigate the double black diamonds of life and love at first sight?
