Jenna Mathews has nothing on her mind except making sure her best friend's wedding is perfect in every way. As the maid of honor and the florist, she needs to keep on task. However, she is in no way prepared for the sexy best man who slides into place at the last second for the wedding rehearsal. He flusters her from the moment he arrives and manages to tip her world on its axis before the night is over. But Jenna isn't ready for his world, and besides, she has family issues to deal with and has no interest in divulging the truth about who she really is.

Mason Simmons can't believe he is falling for a vanilla woman at his best friend's wedding of all places. Even though both the bride and the groom warn him to stay away from the maid of honor, he isn't able to keep his hands to himself. He's a smart man, though. No matter how hard he gets every time he's with Jenna, he still knows she isn't the type to enjoy either of his favorite pastimes - MMA fighting and BDSM. What he really needs to do is get her out of his system so he can move on.

But things don't work out as planned for either Jenna or Mason. Every time they are together, the heat rises. Neither of them is capable of turning the flames down. Jenna proves to be far less vanilla at heart, shocking herself as well as Mason. The fighting is almost more than she can handle, but when Mason takes her to his club, Extreme, she finds herself titillated beyond what either of them expected.

Just when things are looking up, Jenna's family enters the picture to rock the boat. Can their relationship survive the extreme turbulence? Secrets are one thing, but Jenna has a pile she wished she never had to divulge.
