Not necessary.

Random House is currently working on new content for the next parts for owners of the book. The stuff is amazing. I bow to their excellence.

Hmm, there is a book already?

Do I misunderstand the meaning of 'the next parts' referred above when I ask if there has already been some additional content released for owners of the book?   If so, where can I download that? If not, then sorry for the misunderstanding.

EDIT: Nevermind the above!   I never bothered to look at the last pages of the book yet (cause I am still reading it), but I just found out about the serial key in the back of the book. I feel a bit stupid now...

Frog, you lied to me!  WHY?  WHY?  Like the above poster says, our book characters are gone.  Please fix it, buddy.

Thanks - worked OK.

Now I just wish they would stop breaking it with every patch - this should be in the test scripts as it is official content.

Also, Xanders kids are super bad ass.  If you can handle not having anyone able to cast magic until Xanders kids grow up, it's well worth it.  His three abilities are incredible alone, and combined with magic his kids are bad ass.  It sounds over powering, but it's pretty balanced if you consider the work and time it takes to get a full grown kid with a male sov.
