Louise Rennison (1951 – 29 February 2016) was an English author and comedian who wrote the Confessions of Georgia Nicolson series for teenage girls. This series records the exploits of a teenage girl, Georgia Nicolson, and her best friends, the Ace Gang. Her first and second novels, Angus, Thongs and Full-Frontal Snogging and It's OK, I'm Wearing Really Big Knickers were portrayed in a film adaptation called Angus, Thongs and Perfect Snogging. She also wrote a series of books about Georgia's younger cousin, The Misadventures of Tallulah Casey.

She won the Queen of Teen competition in 2008.

Her one-woman live show Stevie Wonder Felt my Face won awards in the 1980s. Her other shows were Bob Marley's Gardener Sold My Friend and Never Eat Anything Bigger Than Your Head.

Rennison lived in Brighton. She was brought up in Yorkshire, in a three-bedroomed council house with her mum, dad, grandparents, aunt, uncle and cousin. When she was 15, her family moved to Wairakei, New Zealand. She attended Brighton University. Rennison was published by HarperCollins Publishers in the UK.

Rennison based much of the material in her books on her childhood in Leeds, where she lived until her family moved to New Zealand when she was fifteen years old.  Many of these experiences come from when she was attending Parklands Girls' High School. After moving to New Zealand she became pregnant and later gave up her daughter for adoption before returning to the UK. She remained unmarried and lived in Brighton until her death.

She lived in a small flat in Notting Hill in her twenties doing an assortment of different jobs until she pursued her dream of acting and enrolled in a Performing Arts course in Brighton. There Rennison wrote and performed a one-woman autobiographical show, "Stevie Wonder Felt my Face." She went on to tour performing this show that was well-received with many awards and even later a BBC show. Along with playwriting, she wrote for a London newspaper writing about whatever interested her, such as how pointless it is to date over 35. Because of these articles, Picadilly Press contacted Rennison and asked her if she wanted to write a teenage diary book. They said her writing was "so self-obsessed and so childish" that she would be perfect to write such a book.

With Angus, Thongs and Full-Frontal Snogging being her first novel, she used real names of people from her childhood as she wrote. She forgot to change the names before the book was published. Rennison said that she writes not in an attempt to teach, but to make herself laugh. She said, "I wanted Georgia to be a decent person. I wanted her to be someone who is a bit stupid and self-obsessed and difficult and funny and rude, and a bit jealous and all those other things. But I wanted her to have a good heart." Rennison also said that her books are not just for teenage girls, but have a "potential resonance beyond the young." In particular, Rennison often brought feminist ideals into her writing. While studying in Brighton she was part of an "all-female cabaret group called Women with Beards," a performing group that poked fun at men and why they are responsible "for all the ills of society while the audience, largely female, would all cheer in agreement." Some similar themes carried over into her novel writing. She wanted her books to get girls talking and deciding for themselves what they want to do and who they want to be not letting men decide for them.

Her death was announced on 29 February 2016.

Responses

Rennison's novels received positive and negative responses. Angus, Thongs and Full-Frontal Snogging received the Michael L. Printz Honor Award in 2001 and has become a worldwide bestseller now translated into 34 different languages. She was also rewarded with the Nestle Smarties Book Prize and the Roald Dahl Funny Prize for the first book in The Misadventures of Tallulah Casey series, Withering Tights.

Despite the positive reception of her novels, Rennison also faced interrogation from teachers and parents about the content she wrote. Often when she visited schools she was well received by the students, but the staff complained to her about the topics she discussed in her novels. However, Rennison rarely apologized for her writing. She sought out 14-year-old girls to talk with them about what they would want to read and wrote that. Her response to these teachers was, "Surely they know what to expect, they know [my books are] all about boys and snogging and all those experiences. What else am I going to talk about?"

In 2007, a guide titled Let the Snog Fest Begin! was released especially for World Book Day. In this, 'Georgia gives her top tips on how to look cool and how NOT to behave if you want to hang on to your Sex God'. A spin-off, titled How To Make Any Twit Fall in Love With You, is available in 10 instalments in 10 days starting 3 March 2011 exclusively through SugarScape.

The story is told autobiographically, through the journal of a teenage girl named Georgia Nicolson. The books detail events in Georgia's life as she grows up in England, along with a group of her close friends known as 'the Ace Gang.'

The majority of plotlines explored in the series follow Georgia and her friends' relationships with boys. A continued theme is Georgia's inability to choose between her initial boyfriend Robbie, the Italian Masimo, and her close friend Dave. The books also narrate the relationships of the rest of the Ace Gang, in less detail, and the impact the main antagonist of the series Lindsay has on these relationships.

A continual source of humour within the series derives from Georgia's family; her promiscuous mother, embarrassing father, eccentric younger sister and violent pet cats provide additional storylines throughout the series.

Georgia's use of language is also somewhat strange, as a glossary is featured in the back of each novel. This was to explain the meaning of her many peculiar phrases, such as 'red-bottomosity' (Georgia's term for unfaithfulness in relationships), as well as things/ concepts that readers from other countries may not be familiar with, such as 'Rolf Harris'.
