How do you convince the uptight girl next door to have some fun? Apply a little heat. 
Meet the next generation of TREX. These rookies bring fresh perspective to the covert agency—like how there's more to life than the job.
She has a plan for everything.
Kayla Riggs is a planner. Her goals in life are simple: graduate college, find the dream job, and settle into her happily ever after. There's no room in her plan for the hot fireman next door she can't seem to get out of her head—or heart. When a fire condemns their building, she's forced into cohabitation with the one guy she's actively avoided since they hooked up.
Except when it comes to him.
Jake Swanson is about to have it all. His dream job as a fireman with the Bainbridge Island Fire Department. A field agent with TREX. He just needs to pass all his tests and graduate. The last thing he needs are any distractions, especially in the form of his uptight, too-many-rules neighbor with the pretty smile. Having her live next door drives him crazy, and not always in the wrong way. Sharing an address with her and keeping it platonic is going to be the hardest test of all. They'll either end up hating each other or falling in love.
There is no other option.
