Science Fiction Stories for Teenage Girls?

Sooner Boomer asks: "Not having met 'Mrs. Boomer' yet, I'm buying Christmas gifts for my nieces and nephews. Whether genetics or just good luck, almost all of the young 'uns are girls. I've been slowly introducing them to the classics of science fiction: Heinlein ('Podkayne of Mars', _'Starship Troopers', etc.), Asimov short stories, Ann McAffrey (the Dragonrider books), Alan Dean Foster (the Flynx books and others), Douglas Adams and Terry Prachett, some Neil Gaiman (Stardust, Good Omens), as well as the mandatory Tolkien and C.S. Lewis. This is just a partial list, but what would Slashdot consider to be good (or even essential) science fiction for teen and pre-teen girls?"

When I was a preteen girl I loved books by William Sleator. It was only years later that I realized how technologically/scientifically advanced they were-- at the time I just loved the stories. My favorites were The Boy Who Reversed Himself (which to this day shapes how I think about 4+ dimensional geometry) and House of Stairs (which I forgot about completely until I was in Psych 101 and then had to track it down and reread it), though they were all good; great plots and characters and cool SciFi. I can't vouch for anything written after about 1990.
