One by One

i can't decide if this was 2 or 3 stars, but i enjoyed the ending a lot and once the pace picked up it was engaging and immersive. but it started so slow, and i had a REALLY hard time caring about any of the characters. two characters that are killed i was like, wait who? also i felt like the app stuff was kind of stupid, and the killer felt too obvious so i kept waiting for a twist to happen. that being said, the story is split between two narrators and i really started to enjoy them both after the halfway point, their perspectives were very interesting and once the pace and tension picked up i felt like i was actually there. loved the setting, but i think some things were just lacking in execution.
