Stabbed In The Back: The Real Sunrise Story, is a fictitious, hard hitting investigative journalistic look into the dark, gritty, underbelly that is Sunrise Studios. Although technically written "anonymously," the website that gives a sneak peak at the book, SunriseSucks.com heavily implies that the book is written by Gale Weathers.
Deductively it is assumed that Gale wrote the book because it directly mentions her website, "galeweathers.com" and that's "where I will reveal more secrets very soon." Also in chapter seven, it is mentions that John Milton the head producer for the Stab franchise "owes Gale Weather [a] significant, [amount of] outstanding cash for the rights to her two books." Which if it was written by her would explain the bad pun about Stab.
