From Here To You by Jamie McGuire

I wasn't sure she could do it, but Jamie successfully delivered a read that I couldn't put down page after page. It was emotional and had a plot that truly just pulled at you.
Jamie has such a twist in her writing that I never quite get this feeling with anyone else. Its just a way she crafts her worlds and her characters that you instantly form strong enough bonds with it that you will find yourself yelling at your book as you read, page after page.
This was also one of those stories that had the perfect blend of chaos and swoon for me. I wanted the out-of-the-bos crazy ex and we definitely got it with this read. I can't wait to get more for this new gang!
Synopsis:
As Darby Dixon sits in a tiny Texas church bathroom on her wedding day holding a positive pregnancy test, she realizes that of all the bad decisions she's made in her life, marrying her abusive fiancé would be the worst. She's never been able to stand up for herself, but she'll sure as hell stand up for her baby. With just the cash she has on hand, she runs to get a bus ticket to the farthest place she can afford. Between her sheer grit and pageant-queen smile, she lands a job as a front desk clerk at the Colorado Springs Hotel. It's not a glamorous life, but she and her baby are all that matters.
A former Marine, Scott "Trex" Trexler has worked in the most dangerous, corrupt, war-torn places on earth. Now he finally has a chance to return to the last place he'd felt at peace--Colorado Springs, Colorado, to take a new job with the Cheyenne Mountain Complex, a top-secret military installation buried deep within the granite.
The moment Trex walks into the inn, Darby knows he's dangerous. There's no way she wants to get involved with another man who seems to be keeping way too many secrets. As charming and devastatingly gorgeous as Trex is, he clearly isn't telling her everything. But as wildfires rage on the mountain and Darby's ex-fiancé shows he isn't so willing to let her go, both she and Trex are soon to find out that what you don't know absolutely can hurt you.
