The Children by Ann Leary (2016)

A rambling Connecticut lake house is the refuge for widowed Joan and her two grown daughters, bipolar concert violinist Sally and near-recluse Charlotte. Charlotte spends her days in the attic working on her very popular, but thoroughly fictional, mommy blog and hooking up with neighbor Everett whenever she can. Into this sheltered environment comes beloved stepbrother Spin with his too-good-to-be-true fiancée, Laurel. Is Laurel all she says she is, or do her lies rival the stories fabricated by Charlotte about her completely adorable but fictional children? A little quirky and humorous, Ann Leary’s The Children provides a glimpse into how the “other half” lives.
