The key normally is to write what you know. If you have never been in any relationship, it can be hard to write about the nuances of a long term marriage. However, if you have raised dogs and care for them, you can create a gorgeous, high quality work of art about dogs and their lives that could not be rivalled by any adult.
Young artists with these talents are often called "child prodigy" or "wunderkind." They are also often gifted, or of above-average intelligence.
Lucretia Maria Davidson, born in 1808 in New York, began writing poetry at age 9 and by the time she died at age 16, she had written 278 poems. Her works were praised by many contemporary poets.
Edgar Allen Poe, famous for his dark writing, was born in 1809 in Boston, Massachusetts. He grew up writing poetry and published his first collection at age 18.
For really famous and dark, go with Frankenstein, written by Mary Shelley when she was 19.
H.P. Lovecraft (of Cthulu fame) was born in 1890 in Rhode Island. He wrote a lot of poetry when he was a teenager, although his first work accepted for publication came when he was 33.
Sylvia Plath was born in 1932, in Boston Massachusetts. She had her first poem published at age 8 and became a renowned poet.
Emily Bronte was born in 1818, in England. She wrote poetry while young but did not begin publishing her poems until age 28. She is most famous for the story Wuthering Heights, published at age 29. She died at age 30.
Emma Maree Urquhart was born in 1991 in the UK. At age 13 she wrote a book, Dragon Tamers, which sold over 100,000 copies in the UK alone.
Jane Austen, born in 1775 in England, is one of my FAVORITE authors. She began her first book - Pride & Prejudice - at age 14. Her first book actually published was Sense & Sensibility when she was 36. She died at age 41.
Speaking of movie tie-ins, when I was growing up I really liked the Outsiders movie with its all-star cast of guy characters. The original story was written by S.E. Hinton when she was sixteen.
Of course there is the very famous Eragon which Christopher Paolini, a homeschooled boy, began when he was 15 years old.
Which brings up a cautionary tale. Many have pointed out that Eragon has MANY similarities to Lord of the Rings and Dragonriders of Pern stories, including names which are almost identical. Some teens tend to borrow ideas for their stories rather than write from their own experiences and imaginations. It is important to be cautious about this.
In 2006, Kaavya Viswanathan (aged 19) wrote a novel How Opal Mehta Got Kissed, Got Wild, and Got a Life which had numerous sections which pretty much duplicated novels by Megan F. McCafferty. Kaavya admitted that she adored the books by McCafferty and had read them several times, and says she must have accidentally copied the phrasing. It is very, very important when you write your own book that you make it completely your own, with your own words and phrasing and ideas.
