Falling for a Santini

As the only girl in my family, I've always had to work harder and faster than everyone else. My five brothers did not take it easy on me, and they still think they can tell me what to do, even who I can date. That's why falling for NCIS agent Jethro Thomas is a big mistake. He's my brother's best friend, and he treats me like a sister.
That is, until I get him alone in my apartment.
One night together, and I know we are meant to be together. But we have to put it on hold because he's going undercover again. The weeks drag on, but when he comes back, JT is a changed man. He's ready for make a go of a relationship with me.
We barely get started on that happily ever after when minor accidents evolve into near death incidents. Both of us realize that JT's last assignment isn't over, and we'll have to stand together to fight for our love.
