His Christmas Wish (Mountain Rescue Romance Book 1) by Melissa McClone

Carly Bishop doesn’t want to come home for Christmas. Hood Hamlet is filled with nothing but heartbreaking reminders of the fiancé and brother she lost six years ago. But her family needs her, so Carly must dig deep to unearth her Christmas spirit so she can give her niece and nephew the best holiday ever.

Mountain rescuer Jake Porter believes he could have saved his two friends that fateful day and kept the Bishop family from experiencing such a heart-wrenching loss. He hopes helping Carly rediscover the magic of Christmas will allow him to finally move forward with his life, but he's not certain anything can relieve the guilt that's kept him stuck all these years.

As Jake and Carly spend more time together, attraction grows, but toe-curling mistletoe kisses aside, his late best friend would never think Jake is good enough for his little sister. But maybe he can open her heart to something else she’s given up on…love.
