Here's a few that caught their attention that stray from the Harry Potter route:
The Abhorsen Series by Garth Nix
(Sabriel, Lirael and Abhorsen)
The Bartimaeus Trilogy by Jonathan Stroud
(The Amulet of Samarkand, The Golem's Eye, and Ptolemy's Gate)
I was depressed to discover that talks and progress of a film adaptation of The Amulet of Samarkand has sputtered to a resounding halt after the early passing of acclaimed filmmakers Sidney Pollack and Anthony Minghella. I still wonder if this film will be picked up again, or if any studio will attempt The Abhorsen series.
