The main characters lacked depth, and there was minimal character development. As a thriller, it fell short of expectations. I even had to speed up the playback to 1.3x to keep it engaging. That said, the narration was excellent and ultimately saved the book for me. It was interesting enough to finish, but in hindsight, I wish I had waited for the library audiobook instead of using a credit. Overall, I enjoyed it, but it wasn’t particularly memorable.
