Tanner Harlow is a talented landscape designer, quietly building a name and a solid future when he finds himself needing to be the temporary guardian to his eleven-year-old half-sister. Tanner loves her, but can’t see himself as a father figure or imagine how he’s going to build his business during his busiest season with a child in tow until his newest client—his high school crush who still makes his heart pound—has a proposition that will help them both as long as Tanner can resist the tempting lure of the girl next door.
