The 66-year-old reality star is reuniting with journalist Buzz Bissinger for the memoir, reported New York Times.
"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," a statement from Jenner reads.
"I couldn't pick a better team, in Grand Central (Publishing) and Buzz, to make sure this story is told with a lot of honesty and care. I made it clear to her before I agreed that everything has to be on the table, nothing can be left out, and I'm going to be interviewing dozens of other people," Bissinger, whose bestselling sports books include Friday Night Lights and The Classic Mantle, added.
