Winter War only has trees on the cover, I don't think it would fit into the picture.
It's a sequel book to the series of the Prince Warriors! It's really good, I actually cried when someone died, I've never done that before...
You've only read the first book? You need to read the others!!!! They're sooo good! Except the last one is sad at the very end though...but still that series is really good. Have you read File Under: 13 Suspicious Incidents? That's my favorite Lemony Snicket book!
@moderators could you merge this post with the one before it? Thanks!
