These are the men of the 94th ID. They fight with honor, they defend their nation and their brothers fiercely, and when they love, they do it with single-minded passion.
Jake Robinson is the most easy-going soldier in his battalion. For the last few months, he’s been watching his friends find love, commitment and even babies . . . but he knows that path isn’t for him. Been there, done that and got the scars to prove it.

Harper Drummond lives and breathes stress. A chef at an up-and-coming restaurant, she works long, demanding hours, and she doesn’t want or need a relationship. But every now and then, she likes to let off some steam under the covers with a willing partner.
The night Jake and Harper hook up is only meant to be a one-time deal. But when they realize they have connections they hadn’t expected–not to mention a chemistry that is downright explosive–they decide that being friends with hot benefits makes perfect sense.
After all, it’s only sex, right?
