Herman Hesse's 'Steppenwolf' is super cool and spiritual in a fantastical way.
suzanne collin's the hunger games!
the dark materials trilogy. xx sy
I love alice in wonderland! did you read the through the looking glass part as well? The only books I can think of that are as whimsical/fantasy like as alice are maybe the narnia books, i dont know if you've gotten into the harry potter books, and perhaps darker but the stephen king dark tower/gunslinger series is fantasy like as well. :]
i've a soft place in my heart for stardust by neil gaiman... or the last unicorn fantasy books with a bit of an irreverent twist :)
Winter's Tale by Mark Helprin. Beautiful magical realist novel about NYC. He writes wonderfully.
