Best sf for children and teens 2007.

Given that sf is getting a very raw deal in the Norton Award, here is my list again.

My top pick has to be Stephen Baxter's The H-Bomb Girl,. London: Faber and Faber, 2007. (parallel worlds, time travel, teens and up).

Runner up: Oisin McGann. Ancient Appetites. London: Random House, 2007. (alternative Ireland, queer protagonist, very strange machines, teen and up).

Other fantastic books:
Bertagna, Julie. Zenith. London: Picador (PanMacMillan), 2007. (post-global warming, pre-teen and up).
Daley, Michael J. Shanghaied to the Moon. New York: Putnam & Sons, 2007. (conspiracy space adventure, pre-teen and up).
Lennon, Joan. Questors. London: Puffin, 2007. (parallel universes, DNA puzzles, conspiracy, queer protagonist, pre-teen and up).
McGann, Oisin. Small Minded Giants. London: Doubleday, 2007. (corporate conspiracy, ice ages, pre-teen and up)
McMullen, Sean. Before the Storm. Melborne, Victoria, Australia: Ford Street Publishing, 2007 (time travel, saving the world, pre-teen and up).
Reeve, Philip. Starcross. London: Bloomsbury, 2007 (steam punk, tale of derring do, pre-teen and up)
Rex, Adam. The True Meaning of Smek Day New York: Hyperion, 2007 (alien invasion, girl and cat save the world, non-white protagonist, pre-teen--unlikely to appeal hugely to older readers).

O.T. Nelson "Award" for insane libertarian sf for kids that has no idea at all how communities really survive in times of trouble:
Pfeffer, Susan Beth. Life as We Knew It. New York: Harcourt Inc., 2006.

Expelled "Award" for telling lies to children about Darwinism:
Coleman, MIchael. The Cure. London and Australia: Orchard Books, 2007.
