The actress, known for playing Katie Sugden on the ITV soap between 2001 and 2015, will release "Princess Phoebe Meets the Tudors", reported Digital Spy.
A summary of the book on Amazon read: "In Princess Phoebe Meets the Tudors, Sammy Winward presents a historically accurate snapshot of Tudor princesses, accessible to younger readers.
"The book presents female characters as strong and self-aware, balanced with the awfulness of Tudor life."
Meanwhile, Winward's exit from "Emmerdale" aired earlier this year.
Winward was also recently cast in the second series of ITV's "Prey".
