Ainsley O'Leary is so ready to get married--she's even found the engagement ring her boyfriend has stashed away. What she doesn't anticipate is being blindsided by a breakup he chronicles in a blog...which (of course) goes viral. Devastated and humiliated, Ainsley turns to her older half sister, Kate, who's struggling with a sudden loss of her own.

Kate's always been the poised, self-assured sister, but becoming a newlywed--and a widow--in the space of four months overwhelms her. Though the sisters were never close, she starts to confide in Ainsley, especially when she learns her late husband was keeping a secret from her.

Despite the murky blended-family dynamic that's always separated them, Ainsley's and Kate's heartaches bind their summer together when they come to terms with the inevitable imperfection of relationships and family--and the possibility of one day finding love again.
