Finding Our Forever by Laura Riley

When art teacher Lizzie returns home from university, she has her sights set on reconnecting with her childhood crush—her older brother’s best friend, Seth. Only Seth isn’t a boy now. He’s a tattooed single father with a young child.
When Seth is hired to renovate Lizzie’s house, he knows his friend’s little sister is off limits, but once Lizzie wins over his daughter as well as his heart, he’ll end friendships, risk homelessness, and even cut a deal with his ex-wife to find their forever.
