Started out slow, but gradually I'm on the edge of my seat. It wasn't necessarily an "oh my gosh" about the daughter who was kidnapped because Lisa Jewell clued us in on the way, but there were some "oh my stars" about the delusions of people. And the end, still reeling.
Quick summary for you: Woman has three children, but one was missing. Divorce ensues, fractured relationships with children. Woman meets man. And things start to unpeel about what happened to her daughter.
I wasn't truly connected to any of the people, except the girl who was missing, but the plot was well brought out and had me guessing as to who to trust.
