Men: let us know about female characters you admire

The fight to stop book publishers from labelling books as gender-specific is on. The Let Books Be Books campaign, launched recently to coincide with International Women's Day, was met with instant success: over 2,000 signatures in one day, authors such as the former children's laureate Anne Fine joining in and publisher Usborne stating that they will "discontinue publication of titles" such as the pink Girl's Activity Book and the blue, robot-themed Boys' Activity Book.

However strong public opinion may be, colouring books which are marketed specifically for boys or girls still sell three times as many copies as books without any sexual categorisation, said the owner of Buster Books in our previous piece. The campaign was launched by the same group of parents who are pushing retailers to cut down on sexism in toys.

One of the misconceptions that they say hamper the potential of kids of either gender is the assumption that boys won't read about girls. To prove that it's daft to think that boys "aren’t capable of empathising with half the planet’s population and irresponsible to market books in a way that suggests they’re not meant to", they are asking boys – of all ages – to share photographic proof of female characters they like.

Here are a few examples:

S.F. Said, children's author: "As a child, I thought she was called 'Alison Wonderland' and I loved her adventures. It never even occurred to me that we weren't the same gender. Now, as a writer, I see that Alice is the first great character of children's literature: an iconic heroine who transcends gender, age and time. Every book I write owes her a debt."

With that in mind, men in our readership, we want to hear from you: what female characters inspired you as kids? And parents, what girl protagonists are sparking the interest of your boys?
