Sometimes our feelings about books are entirely based on our current mood. I read Cinder awhile ago and was only lukewarm about it...but I just reread and it LOVED it! It's funny and clever and unexpected . I never read the rest of the series. Now they're all in my queue! 
 It's kinda sci/fi, kinda dystonian, kinda angsty young adult, and I love how Cinder meshes genres. Fun characters, fun twists, fun idea. Can't wait for more!
