Since I Fell for You (New York Sullivans #2; The Sullivans #16)

Suzanne Sullivan doesn't need a bodyguard. After all, she's one of the most successful digital security specialists in the world--so she can most certainly take care of herself despite the problems she's been running into lately. Unfortunately, her three brothers don't agree. So when Mr. Way-Too-Handsome shows up bound and determined to protect her, whether she wants him there or not, sparks definitely start to fly. Because she has absolutely no intention of falling for the bodyguard she never wanted in the first place. Roman Huson has vowed to do whatever it takes to protect Suzanne Sullivan from harm. And her brothers would kill him for so much as looking at her the wrong way. The only problem is that he's never been hired to work for anyone so beautiful, or brilliant, before. Between trying to keep up with her--and working like hell to keep from kissing her breathless--he's up against the most difficult challenge of his life. Especially when it turns out that the passion, and connection, between them is hotter than anything he's ever known.
