Shut Up and Kiss Me [NOOK Book] by Christie Craig is FREE!
I don't usually promote Nook books but this is my favorite author who writes comedy suspense romances. What I love is almost all her heroes are in law enforcement of some kind or was at one time. I have never been able to put down one of her books till I was finished. I just love her style! So grab this book if you can!
Woot! 
I found it also at Smashwords for free!
