Oh my. That’s all I have to say about this request for a half-forgotten YA anthology.  Jay writes:

hi.. i have been looking for a book that has a collection of horror stories for the pre-teen.. i cant think of the name and only have memory of a few of the stories….. for instance……… one of the stories dealt with a girl who hears an old indian folk lore about a necklace and an indian girl. and she goes in search of this indian girl finds her rips the necklace off her puts the necklace on herself and then suddenly turns into a tree….. also there is a story that deals with a boy swimming in the ocean where the bermuda triangle is… he is swimming under water and notices a door.. goes in and discovers all the lost ships and planes but discovers it is inhabited by vampires of sorts… if you could help me find this collection of stories i would be most grateful.

It seems like this would be a hard one to forget, if you had ever encountered it. Can anyone help Jay out?
