This book has stuck with me into adulthood. I read it at some point in middle school and I eventually think about it since it explores dimensions beyond 3d. Definitely is a great book for a middleschooler to read. ( )

Well, the title and cover are somewhat misleading, as the main character is a girl. There are two boys though so I guess it's ok - we need to appeal to those male reluctant readers after all. You do need to be willing to read SF to enjoy this, because, though the characterizations are indeed quite wonderful, the bulk of the action takes place in '4-space.' You *don't* need to fully understand how the different dimensions work, or the details of all the action there. Just ride it out, the way the boy on the cover is doing, and you'll be fine. Thrills, chills, and giggles for ages 12 up. ( )

There’s a new kid at Laura’s school. But he’s not just weird; he’s downright creepy. When things start appearing in her locker when no one knows the combination, and some are written backwards in “mirror writing”, she sets out to discover the truth about Omar, and herself, and finds herself in a terrifying world from which she may never escape.

This was an unusual premise and I really liked the sciency bits, and the visual explanations of tricky concepts. The plot was a little forced and the characters – no pun intended – one-dimensional. I couldn’t really sympathize with Laura, the narrator. ( )
