Blue Sky

Beautifully written, this reads like literary fiction to me (though, admittedly, I don't read in that genre). There's an airy, dreamlike quality to the prose that lets you drift through most of the story (which is great for bedtime reading). Sky is a strong and curious character that's easy to root for.
A couple of notes - Sky said "oh" quite a bit. Reading this out loud, it became a bit redundant after a while, though not enough to totally distract from the story.
Also, I found I wasn't terribly fond of the ending. Though it showed Sky's strength, she never really made her decision, not fully. It was kind of made for her. She didn't accomplish her one goal, and instead seemed to wander from the very possibility as it presented itself in the end. I felt myself wanting for something a little more solid, and a little more satisfying than what I got.
Otherwise, an entertaining read and a sweet story for young readers (or anyone who enjoys character driven literary fiction).
