"Glee" season 6 spoilers reveal the return of Sam Evans to McKinley High as cast Lea Michele gears up to become the New York Times bestselling author once again.

The E! News reported "Glee" season 6 spoilers when it confirmed that Chord Overstreet is coming back to reprise his role as Sam.

Overstreet told the website that he would go back to work in September and "I assume I will be in all of the episodes"

E! News observed that there's a lot of secrecy surrounding the plot and cast members of the last season of "Glee."

Earlier, TVLine dished out "Glee" season 6 spoilers when it reported the addition of five new characters.

The characters would all be McKinley sophomores and they include Roderick (described as a chubby boy with a voice like Otis Redding); Spencer (the "new resident football stud" who just happens to possess an incredible voice); Jane ("righteous, ambitious and unconventionally pretty").

Jane is "funny because she doesn't have much of a sense of humor. She wanted to be a Warbler but tradition kept her from joining so she jumps ship to the New Directions."

Then there are Mason and Madison who are considered as "twin Cheerios." They're super-positive and extremely weird. Mason gives off a gay vibe.

Meanwhile, Lea Michele wrote on her Twitter on August 15: "Working on book number two today! Had so much fun writing #BrunetteAmbition, I'm so excited for you guys to read this next one!"

But the actress did not reveal any more details on whether her second book would be a follow-up to the "Brunnette Ambition" or it would be an entirely different book.

The "Brunette Ambition" debuted at No. 3 on the New York Times Bestsellers list, trailing only "Instinct" by T.D. James and "Grain Brain" by David Perlmutter with Kristin Loberg.

In her book, Lea Michele wrote: "This book is the story of how I got to where I am today. My hope is that something from it will inspire and motivate you, and also make you realize that anything you want to accomplish in your life is completely possible."
