Maverick's Full House — Tara Taylor Quinn

Making room in his heart for one more… 

Cowboy Noah Trent can do hard things. The divorced dad is raising triplet toddlers on his own and helping his folks run Stargazer Ranch. Kids and cows -- those he can handle. Lucy Bernard is another story. She's the boys' day care teacher, and it would be way too easy for Noah to fall for her. But sorry experience has taught him that love doesn't last. Lucy, however, is all in. She knows she belongs with the Trents, and she will do whatever it takes to convince the stubborn rancher she's ready to take on parenthood, ranch life -- and him!
