Family life is enough of a juggle without … The In-Laws

Amanda. Katie. Melanie.

Three wildly different women with one big problem – their impossible mother-in-law, Nancy.

When an unexpected crisis hits the family business, the sisters-in-law find themselves navigating stormy waters. Amanda is back in town and ready to reclaim her spot at the top. Katie, the feisty outsider, knows she’ll never earn Nancy’s approval – and has stopped caring. Melanie, ambitious and savvy, is more than capable of running the business, if only Nancy would loosen her iron grip.

Forced to confront messy truths about marriage, motherhood, succession and family loyalty, the three women soon realize their greatest strength might just be each other.

The In-Laws is a sharp, funny, and relatable novel about surviving the family you didn’t choose.
