Slow Burn by Dee Ellis

Levi Holt’s an old soul. Married fast, he hoped to build a life with his wife and fight fires with his brothers. Too bad his wife didn’t get the memo that a wedding band meant her Badge Bunnie ways should have ended. Just after the ink is dry in his divorce, he finds a new girl stealing his heart. The tiny baby that his former wife swears is his. Now Levi’s old soul is uncertain if he’s the right guy to raise the little angel.

Brynn Gold is in Chicago for all the wrong reasons. Any reason, really. No one needs to know why she doesn’t want to go home. Especially not the tiny angel that she agrees to help Levi take care of. That adorable baby, and Levi himself, make her heart burn with what she had to give up. Something Brynn doesn’t think she should get to feel the warmth of ever again.

Levi thinks she does and he’s willing to risk getting burned again to prove it
