The Westing Game, by Ellen Raskin... LOL, that *does* bring back memories!
Many, many of the books/series mentioned here bring warm smiles of nostalgia. But since this thread is supposed to be for the all-time favorites, I'll restrict myself to three:
Watership Down, by Richard Adams. Kind of a given, considering my nick and avatar!

I read this to my little sister when she was ten and I look forward to reading it to my own children, sometime after I finish reading...
Laura Ingalls Wilder's books to them. Mind you, the last few are too old for them at the moment.

Grey eyes and dark hair still sound good to me!
Hazel, who also liked
To Kill a Mockingbird and
The Phantom Tollbooth and the Narnia books (although, as an adult, I was a little taken aback at just how *blatant* the Christian allegories were) and Madeleine L'Engle and Graham Martin's
Giftwish and
Catchfire and the Hardy Boys and Asimov and the first few Pern books and Francis and Rex Stout and
Scarlet Pimpernel and
Macbeth, for some reason, and Ngaio Marsh
Mrs. Frisby and the Rats of NIMH and a few Agatha Christies and Terry Pratchett and Lois McMaster Bujold and Eddings'
Belgariad (although not the other books) and Gordon Korman's child and teen books and the Harry Potter books and Mary Stewart's
Crystal Cave and
Hollow Hills and
Anne of Green Gables and Gillian Bradshaw's
Hawk of May and... oh, never mind, just call me a literary omnivore.
