The letter from a six-year-old girl that changed an entire publishing series

When Parker Danis was six years old, she realised the book she was reading about glow in the dark bugs wasn't meant for her - because it was part of a series called the 'Biggest Baddest Books for Boys'.

She decided to write a letter to the publishers, ABDO publishing, to complain.

As Danis' local paper in California, the Milpitas Post reports, this is how it read:

Dear Publishers:

I am a 6-year-old girl and I just read the 'Biggest, Baddest Book of Bugs.' I really enjoyed the section on Glow in the Dark bugs and the quizzes at the end. When I saw the back cover title, it said 'Biggest Baddest Books for Boys' and it made me very unhappy.

It made me very sad because there's no such thing as a boy book. You should change from 'Biggest, Baddest Books for Boys' into 'Biggest, Baddest Books for Boys and Girls' because some girls would like to be entomologists too.

Parker sent her letter on 2 April - and had a response from the publishers 20 days later:

You brought up a very good point: there should certainly be a 'Biggest, Baddest Books for Boys' for everyone. After all, girls can like 'boy' things too

We have decided to take your advice. Next season, we will have a series simply called, 'Biggest Baddest Books'

• ABDO's response to Parker Danis

Last month they sent her a package with books from the new, re-titled series.

Parker, who is now seven, had this to say about her victory.

I think ABDO learned a lesson ... . If boys want to, boys can have long hair, and girls can have short hair.
