My recommendation for ファンタジー series enthusiasts is the
link によって Isobelle Carmody. Fascinating, detailed and exciting read. It follows the exploits of young Elspeth Gordie, a misfit in her post-apocalyptic village because she has mental talents that are considered to be "mutations." She's sent to Obernewtyn, a complex in the mountain which is part prison, part laboratory. Elspeth, along with her friends, uncover the secret motives of those who run the complex, and the darker mystery beneath it all.
