The Keeping Up With The Kardashians star has been approached by publishing houses eager to secure a deal for her life story, according to US Weekly.
A source said: "Caitlyn is in a great place right now. She's very happy. Life is good."
Caitlyn - who previously published two books about her Olympic triumph - has had a very good week, as E! also announced it would be renewing her reality show I Am Cait for a second series.
The groundbreaking documentary followed Caitlyn as she adjusted to life after her transition, while also raising awareness for the transgender community.
Back in June, after Caitlyn went public with her transition, an article by Entertainment Weekly delved into what a publishing deal with the 65-year-old may be worth.
At the time, experts from the industry predicted Caitlyn could secure an advance of $10 to $15 million for her life story, although one expert suggested she should wait for at least a year before publishing, as she already had the platform of Vanity Fair, Diane Sawyer and I Am Cait.
