The book follows Alix Summers, a podcaster who meets Josie Fair, her birthday twin. After a chance meeting, Josie convinces Alix to start a podcast about her life, which seems interesting but quickly takes a strange turn. As the two women’s lives become more connected, things start to unravel.

The book starts off strong with an interesting idea, but it has a few big problems. One major issue is how it handles a character named Walter whose pedophilia is excused because of his role as a "good father," which doesn’t sit well, especially with how a 13-year-old victim is portrayed. This doesn't feel right, and it makes the story uncomfortable.

Another problem is the way the book jumps between characters and timelines. It’s hard to tell who is doing what, and it gets confusing. The plot feels messy, and the story doesn’t build up to the exciting twist that you expect. Instead, it just ends without any big surprises.

Overall, the book is entertaining in parts, but the confusing structure and the way it handles serious issues make it fall short.
