Graveyard Moon by Carol Gorman (1993, Paperback)

I bought this book because I always checked it out at my local library, finally decided to buy it rather then always having to check it out and return it.

This is a suspence book, some might even say a bit of horror.

Kelly is moving in with her grandparents away from the town and friends she grew up with. Starting a whole new school she was forced to make friends, renew her life.
Her first interation with a group of girls was an initiation, they were to go to a cemetary where the others got a friend to play dead. When Kelly saw him he was to leave. All was good and planned until the next morning when they found out he died later that day.
The last one to see the boy alive Kelly is split between what to do.
Among that she also has Miles, a trouble maker at school who keeps watching her. And as it turns out he was in the graveyard that night.
This book has you questioning whether Miles is good or bad, who could have been the murderer, what were the motives and what is Kelly going to do.

If you like a suspence book, this is for you. All the way until the little twist in the end.
