Sonnet Romano's life is almost perfect. She has the ideal career, the ideal boyfriend, and has just been offered a prestigious fellowship. There's nothing more a woman wants, except maybe a baby brother? When Sonnet finds out her mother is unexpectedly expecting, and that the pregnancy is high-risk, she puts everything on hold, the job, the fellowship, the boyfriend and heads home to Avalon. Once her mom is out of danger, Sonnet intends to pick up her life where she left off. But when her mother receives a devastating diagnosis, Sonnet must decide what really matters in life, even if that means staying in Avalon and taking a job that forces her to work alongside her biggest, and maybe her sweetest, mistake, award-winning filmmaker Zach Alger. So Sonnet embarks on a summer of laughter and tears, of old dreams and new possibilities, and of finding the home of her heart. At once heartbreaking and uplifting, Return to Willow Lake plumbs the deepest corners of the human heart, exploring the bonds of family, the perils and rewards of love, and the true meaning of home.
