I always liked the Richard Peck books. There were two books that involved ghosts; the second one had a girl who was a medium seeing the dead from the Titanic, IIRC. I'll have to look that one up for its title--it was really excellent!
Literary Buffistas 3: Don't Parse the Blurb, Dear.
There's more to life than watching Buffy the Vampire Slayer! No. Really, there is! Honestly! Here's a place for Buffistas to come and discuss what it is they're reading, their favorite authors and poets. "Geez. Crack a book sometime."
Sideways Stories from Wayside School. The Great Brain. Matilda. Anastasia Krupnik. Nate the Great. No Flying in the House. Mrs. Frisby and the Rats of NIMH. I guess she's still a little young for From the Mixed-Up Files of Mrs. Basil E. Frankweiler.
Oh, that's Ghosts I Have Been, I think, Kathy! I loved that. Richard Peck and John Neufeld were huge staples for me.
I'm bookmarking all of these because they're awesome.
Harriet the Spy Where the Sidewalk Ends Nancy Drew(although I might have been a little older for those...)
Is she too young for Edward Eager, Sox? Because I really enjoyed them, and I think if she likes Narnia, she'll like those, too.
Ghosts I Have Been
Yes! Such a good book. It was spun off from The Ghost Belonged to Me, which is also excellent.
Elizabeth Enright! Gone-Away Lake! The Melanies! The Four Story Mistake!
Though I'm not sure of the proper age group on those.
Ooh, I loved Elizabeth Enright, though got a bit confused over some of the old-fashioned terminology. Also loved Edward Eager. And E Nesbit!!
