Rescue Me by Susan May Warren

From the publisher:
When Deputy Sam Brooks commits to something, nothing can sway him--not just on the job as liaison between the Mercy Falls sheriff's department and PEAK Rescue, but in his private life. He's the one who stuck around to take care of his mother after his father's accidental death. And he's the one--perhaps the only one--who believes Sierra Rose is the perfect girl for him. Safe, practical, and organized, she's nothing like her hippie, impulsive, bleeding heart sister, Willow.

Willow, however, has been in love with Sam Brooks for as long as she can remember. But she wants her sister to have a happy ending. Besides, Willow has other things to focus on--namely, nabbing the job as youth pastor for her small-town church. Best thing for her to do is to purge Sam from her heart.

Neither can predict the events that will bring them together in a fight for their lives in the forbidding wilderness of Glacier National Park. Stranded, injured, and with the winter weather closing in, Sam and Willow will have to work together to save a crew of terrified teenagers. As they fight to survive, they might just discover a new hope for love.

This is book 2 in the Montana Rescue series and I definitely think you should read book 1 before this one (although you can still enjoy this as a stand-alone) because you will enjoy this book so much more when you have more of the back stories. 

Susan May Warren is such an enjoyable storyteller!  I couldn't wait to begin reading this book and once I started I didn't want to put it down.  I love that the whole story was over a relatively short period of time, because I felt you could really get to know the characters.  Willow's character was so lively and lovely.  I just wanted to be her friend.

I recommend this book and series to others.

I received this book free from the publisher.  All opinion expressed are my own.
