We Can Forever by Lenna Phoenix

Michael Greer is a second-generation fire chief and a single dad of a precocious 11-year old, so there’s not much that scares him.

(Admittedly, more because of the second than the first.)
When Pine Island’s new craft shop owner accidentally backs into his car, he takes that in stride too. And does what any fire chief would do.
Invite her out on a date.
It doesn’t take long to figure out that Hannah Lewis is gorgeous, quirky, smart as hell, and…hiding something.
Hannah has learned the hard way to keep the truth about her life as hush-hush as possible.
At best, people don’t understand. At worst, they call her lazy or a liar.
Better to just keep her secrets to herself and keep her distance from almost everybody.
But this tiny town’s sexy fire chief won’t seem to accept her attempt at solitude. He keeps showing up all patient and witty and a great dad. Everything Hannah has ever hoped for if she allowed herself to admit it.
He says he’s ready to fight her battles with her.

Will he still feel that way when he finds out the truth?
