White Wedding (The Guardian Agency #1)
Ursula Sinclair

She runs away from her life, and a chance encounter with the gorgeous, successful Ross Marshall leads to a week of passion and a connection neither of them expected. Ross seems determined to have a future with Shanna, but someone out there won't let it happen. Shanna returns home and soon discovers disturbing secrets about the people she trusts.
With so much stacked against her, she looks to Ross for protection and comfort, and it turns out he may be exactly what she needs - except the man she left at the altar isn't giving her up without a fight.
