If you thought "Fifty Shades of Grey" was erotic, think again. Another author is claiming that her biography is way better than E.L. James' steamy trilogy.

Janis Hetherington recently launched "Love Lies Bleeding: Memoirs of a Sexual Revolutionary" last month. The autobiography contains "adult material and explores her life from being expelled from school at 16-years-old, to joining left-wing theatre group Unity and becoming a Parisian brother-keeper," according to Banbury Guardian.

"The book is much more erotic than 50 Shades of Grey because it is a true story - the book explores a lot about life in the 1960s including police corruption and the brutality of brothels," Hetherington said. "The subject of artificial insemination was something that was a main talking point at the time, before test tube babies. People did not know it was not difficult to do something like this."

The difference here is that James' story of Ana Steele and Christian Grey having steamy, kinky, BDSM sex in the Red Room of Pain is fantasy, while Hetherington's book is non-fiction and events that took place in real-life. It depends on which suits your taste.

The 350-page autobiography, published by Mira Publishing House on Oct. 10 is described:

This is a true story of a child born into a Middle Class (albeit dysfunctional) family in Middle Class Home Counties England in the Middle of the last century who came to be anything but 'Middling'. As the Child attempts to understand her Sado/Masochistic fantasies from the age of four she soon realizes her lack of fear of punishment empowers her. Her journey, often involving Headline Stories and Old Bailey Trials gave her many names. The Countess, The Whore, The Sadistic Pervert, Lesbian Mother, Freedom Fighter, HumanRight's Campaigner, Peace Tree Planter. They are all parts of a unique whole, encompassing four decades. She survived to fight Court Cases brought by corrupt Police and Win, to see the Gangs controlling the London of the sixties imprisoned knowing and indeed living with part of their legal team. She understood intimately the need for Mafia money to control the Gambling Dens in Wilson's London and the Honey traps used by the USA in Europe to 'fight' the Cold War paranoia of that decade of so called Free Love.

"It has taken me 35 years to finishing writing this book so I 
hope it doesn't take another 35 years for people to put it on display!" Hetherington said. "Fifty Shades" definitely didn't take that long.
