Up in Smoke by Joanna Rose

Do you believe in second chances?

During his first solo entry into a burning house, Aiden finds something he hadn’t anticipated: Emily Young, the woman he’d long ago loved and lost.
After a high school heartbreak from the infamous Aiden O’Connor, Emily decided on a solitary, minimalistic life writing romance novels. The last thing she’d expected was to be saved by the man who shattered her heart eight years ago—a man she’d long ago decided never to trust again. But a lot changes when she finds that Aiden O’Connor is no longer the teenage boy she’d loved. He’s a jaw-dropping firefighter who could be mistaken for one of the steamy characters in her romance novels.
After losing her house to a fire, falling a month behind on her novel’s deadline, and receiving unnerving fan letters, Aiden isn’t all Emily has to worry about, but he certainly adds to the pot.
He may have fooled her once, but Emily doesn’t give second chances.
Not even for a handsome, kind-hearted, chivalrous man.
Not even for Aiden.
