Louise Rennison, author of the beloved Confessions of Georgia Nicolson series, has died.

Rennison’s publisher, HarperCollins, confirmed her death on Monday, February 29.

They released a further statement on The Bookseller, saying, “Nobody wrote for teenagers like she did, she understood them, their lives and their extraordinary and powerful friendships. In life, as in her writing, she brought joy and laughter. Our thoughts are with her family, friends and the readers whose lives she has touched for almost 20 years.”

The executive publisher for HarperCollins’ children’s division, Ann-Janine Murtagh, added, “Publishing Louise was a joy. She was beautiful to know and saw the funny in everything. Bold, brave, irreverent and wise, she leaves us with a million happy memories and a legacy of laughter with her wonderful books.”

Rennison’s first and second novels in the Georgia Nicolson series, Angus, Thongs and Full Frontal Snogging and It’s OK, I’m Wearing Really Big Knickers, were both adapted for film, introducing a whole new generation of audiences to her work.

Several episodes in the Georgia Nicolson series were allegedly based on Rennison’s life in Leeds, where she was raised in a three bedroom council house with her mom, dad, grandparents, aunt, uncle and cousin. Georgia Nicholson grew up alongside countless teenage girls the world over, offering them a humorous outlet via her various exploits with the Ace Gang.

Tributes have begun pouring in, commemorating her particular brand of wit and inspiration for aspiring authors.

Rennison was the recipient of the Queen of Teen award in 2008, and the Roald Dahl Funny Prize in 2010 for her spinoff novel, Withering Tights, part of a series about Georiga Nicholson’s cousin, Tallulah Casey.
