Patti Davis, the daughter of Ronald and Nancy Reagan, has penned a new novel, “Till Human Voices Wake Us,” a lesbian love story written in the first person.

“Till Human Voices Wake Us” is available digitally on Amazon and was self-published by Davis. Although she isn't a lesbian, Davis has previously admitted her own liberal views clashed with her president-father's conservative political stance. The New York Post notes Davis posed for Playboy in 1994 when she was 41 and has dated Eagles founding member Bernie Leadon. She also has battled drug addiction and celebrated her recovery by posing nude in More magazine in 2011, according to the Independent.

Davis describes the process involved in trying to get “Till Human Voices Wake Us” published. “I've written a lot about my famous family, the Reagans -- maybe this nonautobiographical novel was too much of a departure for publishers to wrap their heads around.”

Despite interest from publishers, there were no offers for “Till Human Voices Wake Us,” she said. It can be downloaded on Amazon for $2.99. In addition to her latest novel, Davis is the author of several other books including an autobiography and several works of fiction.

She told the New York Post that “Till Human Voices Wake Us” probably won't be the latest entry in the popular “mommy porn” genre. “I didn’t want to write ‘Fifty Shades' of whatever,” she says, calling her novel a “love story.”

“Till Human Voices Wake Us” is about a mother who loses her husband and falls in love with her sister-in-law, Iris. The novel starts out with an epigraph from T.S. Elliot, “We have lingered in the chambers of the sea, By sea-girls wreathed with seaweed red and brown, Till human voices wake us, and we drown.”
