Katelyn's body was found by her mother shortly after her death. She was electrocuted by an espresso machine in the bathtub. Everyone is shocked to hear of her death--although it wasn't unexpected.
Twins Hayley and Taylor are convinced it wasn't suicide. The twins get feelings every so often that often turn out to be true. So they decide to figure out what happened to Katelyn, and who did it. They need to be careful...they don't want someone to find out about their special talents. There is already a reporter snooping around, connecting the three girls to the bus accident that happened when the girls were 5. Every girl on that bus is now deceased...except for the twins.
As the story moves on, more and more secrets are revealed. It takes a while to really get into the story...I wasn't sure where it was going at all. The chapters are mostly short and easy to get through, although the foreshadowing at the end of most of them got old.
The author talks a lot about evil, but that doesn't really go anywhere. The story was "inspired" by the events that have surrounded the deaths of many teenagers who have been bullied or harassed on online social networks by parents of other teenagers.
