"The only legend that is not part of the Quileute tradition is the part I devised specifically to fit the Cullens."

The Twilight Saga: The Official Illustrated Guide - Stephenie Meyer

I found this book to be very interesting and truly enlightening. I think my favorite part was the interview Stephenie gave at the beginning of the book. I also really enjoyed the personal histories. I feel that it is well worth reading. It is a nice companion to the series.
