My books came in yesterday! It's fo real, folks!
So far I've noticed
[spoiler]
-The scene where Jake "thinks" and Tobias "hears" his thought speech has been changed to say that it only works when you're morphing
-"I have a Sega at home" is changed to "I have a system at home"
-A few grammatical changes, like a comma deleted, the phrase "mall area" changed to just "mall".
-The word "cloned" changed into "fused" to describe Elfangor looking like someone had fused a person and a deer together.
-There is no inset cover picture, and the pages don't "morph" when you flip them.
-The back phrase that everyone knows and loves has been cut down to something to the effect of:
"We can't tell you who we are. Or where we live. It's too risky, and we've got to be careful. Really careful. But everyone is in danger. Yeah. Even you."
[/spoiler]
I haven't gotten much farther, but it'll be interesting to see what other changes crop up.
*happy dance* Morphing covers!
