ABANDONED. girl who becomes a ghost tries to learn how to use her powers

[Monster]

Hey there!

I'm looking for a book I read in middle school - it was YA fiction, about a young girl who died, and went through the process of being a ghost.

The most vivid thing I remember was that someone could hear/see her, and tried to get the other kids in the friend group to collect blood in a bowl for her, because it was supposed to help her improve her ghost-powers (moving things, opening doors, talking audibly to the living, etc).

Don't remember the ending, or the author/title.

Thanks for any help!

Did you mean to leave the group after posting this? Since you have, this gets moved to Abandoned. But if you rejoin we can move it back to Unsolved.

It's been years since I read it myself, but could it be Remember Me by Christopher Pike? This version says published 2010 but it was way before that (another edition) as I read it as a teenager too.
