The Lake sisters are perfect opposites. After their mother died and their father was lost in grief, Willa had no choice but to raise her sister, Harper, and their brother, Lucas. Then, as an adult, she put her own life on hold to nurse Harper through a terrifying illness. Now that Harper is better and the sisters are living as roommates, Willa has realized her dream of running her own bakery and coffee shop, bringing her special brand of caretaker to the whole Oceanside community.

Harper, on the other hand, is always on the go. Overcoming a terrible illness has given her a new lease on life, and she does not intend to waste it. When Harper announces her plan to summit Mount Rainier, Willa fears she may be pushing herself too far. Harper, for her part, urges Willa to stop worrying and do something outside of her comfort zone—like taking a chance on love with a handsome new customer.

Sean O'Malley is as charming as he is intriguing—a freelance photographer whose assignments take him to the ends of the earth. Soon Willa's falling for him in a way that is both exciting and terrifying. But life has taught Willa to hedge her bets, and she wonders whether the potential heartache is worth the risk.
