I brought this one with me during my vacation, and it turned out to be a great choice for an 8-hour car ride – I didn't want to put it down. I wasn't sure what to think when reading the summary, but it was surprisingly good. I'd say it was more of a low-key thriller. It almost sneaks up on you. It's not so obviously intense where you sense a plot twist coming. It's more subtle and seems to come out of nowhere, which is almost more disturbing.
