What do you do when you’re already a reality television star, a Time magazine “Person of the Year” and Barbara Walters’ “Most Fascinating Person of 2015”?

If you’re Caitlyn Jenner, the world’s most famous transgender person, you write a book, of course.

Grand Central Publishing announced Tuesday that it has acquired a memoir by Jenner, 66, to be written with journalist Buzz Bissinger and tentatively published in hardcover and audio editions in spring of 2017. The book has no title at this point.

Jenner, already known to millions as Olympic decathlon champion Bruce Jenner and as a regular on the E! network’s “Keeping Up with the Kardashians,” made international headlines last year for transitioning from male to female. Her transition was covered in an interview with Diane Sawyer, a Vanity Fair cover story written by Bissinger and a TV documentary series, “I am Cait.” The second season of the show begins March 6.

“Things have been moving so quickly that it will be nice to slow things down a bit and take the proper time to reflect on this journey,” Jenner said in a statement released by Grand Central.

Bissinger, who wrote the book “Friday Night Lights,” the basis for the TV series, said he anticipates that the book will “reveal all the complexities and twists and turns of her life from boyhood to transition.”
