Nobody But You by Megan Green

Former firefighter Mason Cooper knows how it feels to be burned, both by life and by flame.
Still, nothing could have prepared him for life’s ultimate task—single fatherhood. As the sole provider for his little girl, there’s simply no room in his carefully constructed life for distractions.
When a stray dog lands him in the office of the new local vet, Mason comes face to face with a major complication. Because the new vet in town is none other than his childhood friend, Madeline Woods, the same girl who up and left him without a trace.
Gorgeous, smart, and thoughtful—the more time Mason spends with Maddy, the more he finds himself questioning whether she’s the thing he and his daughter have been missing all along.
But being with Maddy is like playing with fire, and while a little heat might be nice, can he trust her not to burn them both?
