A steamy military romance with a touch of suspense and a very cute drone
Burke
Before Cass dropped into my life, I had no idea smart girls could be so much fun.

I can't get enough of her — or the way her mind works. And I can't imagine being bored ever again.

My new self-assigned mission is chasing after her. Particularly now that strange and dangerous things are happening around the camp. It would be considerably easier to keep her safe if she followed orders.
One of these days, maybe she'll believe me when I tell her I'm here to stay.
Cassidy
I have a job to do here and a personal, secret mission that feels critical to my future. I thought Burke was someone else when I tried to spy on him.

Now I can't get rid of the guy, even though I explained it was a simple case of mistaken identity.

He's gorgeous, charming, and sweet. Also, overprotective and bossy, if you like that kind of thing.
There's no way this can last.
Challenging Burke is the second book in the ACI Unleashed series.
Every year, ACI holds its annual summer war games to test tech and strategy (and play in the mud). This is the first of the books set on Embrace Island in the Pacific Northwest. While the mystery spans several books, so reading in order will be helpful, there's no cliffhanger for Burke and Cassidy. They'll get their HEA in this book!
