Here’s what I remember:
- A girl meets a strange nerdy boy who can go into the 4th dimension
- The fourth dimension wasn’t just a perpective, it was its own universe with its own living creatures
- If you flip over in fourth dimension and come back, you will be reversed, and all foods taste weird to you. Apparenly, reversed ketchup is like crack
- The guy and gal are kidnapped by two freaky creatures in the fourth dimension, and then they look at them with fourth-dimension viewing glasses, they looked like scary octopuses
- This book ruled
I think this author wrote another book about a boy that finds a cloning machine. Except the clone would start growing weird black moles and turn into a freaky killer. Or maybe that was a bad dream I had.
