Twilight knows something is up. It's been 6 years since the major flood, and Equestria finally had peace again, but she felt something was just not right. The Tree was gone, but she had a feeling that it left them something. But that's not all, her friend's kids all seem to have something in them. She just can't make out what it is.
No swearing or really bad stuff, but it's Teen because of a war that goes on at the beginning and end of book. Oh and, includes rude humor.
