There are some great books in the genre but these are not for me. Try the Rescue Me Saga from Kallypso Masters. In fact, I read the series last summer! It has it all, hot marine heroes, a little kink and lots of romance too. She's got a great deal going right now too. You can get Books 1 and 2 in one volume for just $0.99! That's a bargain! Here's the link for amazon: Masters At Arms & Nobody's Angel. You can thank me later.
