A "Supergirl" actress has written a children's book that she says she wished she had as a child, according to The New York Times. The newspaper reported the story on Thursday, 29 October 2026.

The New York Times did not name the actress in its headline or summary, and further details of the book were not available in the reporting. The title, publisher and release date have not been confirmed in the material reviewed.

The announcement places the actress among a growing number of screen performers who have moved into writing for young readers. According to The New York Times, her motivation was personal: she wanted to create the kind of book she had looked for growing up but could not find.

The report frames the project as one shaped by the author's own childhood reading experience rather than by an existing series or franchise. No information was given about the book's subject, its intended age group or whether it draws on her acting work.

Watch for the actress's name and the book's publication details to be confirmed as coverage develops.
