O Christmas Knight by Em Petrova
This is hot, intense, entertaining and romantic. Bo is is strong, determined, bold and caring. Tyler is tough, stubborn, unpredictable and smart. Finding Tyler in the situation she was in almost gave Bo a heart attack, and kicked his brotherly concern into high gear. Then she shocked him by turning his world upside down then running away. But he wasn't about to let her get away with that because he was twisted up inside over her. Tyler didn't think that it was a good idea to have anything to do with Bo, but she stopped thinking every time he was close. Bo turned out to be less strange than I thought he was, sexier too. This is one of the best stories in the series.
