Hannah Russell's carefully crafted plans for her life have been upended without warning. When her best friend died suddenly, Hannah became guardian to a five-year-old named Noah. With no experience at motherhood, she's terrified she's not up to the challenge. She and Noah need time to get to know each other, so she decides to rent a country house with stunning views on a like in rural Colorado. When they arrive at the house, they are greeted by the owner, a handsome man who promises to stay out of their way. But his clumsy Great Dane, Romeo, has other ideas and Noah immediately bonds with the lovable dog. As Hannah learns to become a mother, Owen Abrams, who is recovering from his own grief, can't help but be drawn out of his solitude by his guests. But life throws more challenges at this unlikely trio and they are tested in ways they never thought possible. All three will discover their strengths and, despite their differences, they will fight to become a family. And the people of Sullivan's Crossing will rally around them to offer all of the support they need.
