The story Curtis Jackson better known as 50 cent will pen, is about a 13 year-old bully who learns to mend his ways after witnessing the harm he caused, according to Penguin Young Readers Group.

It is partly based on 50 Cent's own life. The rapper grew up in the New York City neighbourhood of Jamaica, Queens and in an area that had heavy crime during his youth.

"I had a strong desire to write 'Playground' because I wanted to explore how a kid becomes a bully," 50 Cent, who has a teenage son, said in a statement.

"I drew on events from my own childhood and adolescence, but was excited to see the story take on its own life," the rapper said.

50 Cent began winning fans in the late 1990s with songs like "Thug Love" and "How to Rob," but after an attempt on his life, his record company dropped him. He staged a comeback in the early 2000s with his album "Get Rich or Die Tryin'," and since then he has recorded albums and performed in movies.

He published a 2005 autobiography called "From Pieces to Weight" and followed that in 2009 with a life strategies book "The 50th Law," co-written with Robert Greene.

Even though the rapper, who has sold over 22 million albums worldwide, hopes to discourage teens from bullying, he has engaged in his share of public feuds over the years.

In 2009, he traded barbs with rapper Rick Ross, taunting him in lyrics and on video for formerly working as a corrections officer. Before that, 50 Cent traded insults with rappers The Game and Cam'ron, among others.
