Summary from Wikipedia

Born in Portsmouth, Dickens left school at age 12 to work in a boot-blacking factory when his father John was incarcerated in a debtors' prison. After three years, he returned to school before beginning his literary career as a journalist. Dickens edited a weekly journal for 20 years; wrote 15 novels, five novellas, hundreds of short stories and nonfiction articles; lectured and performed readings extensively; was an indefatigable letter writer; and campaigned vigorously for children's rights, education, and other social reforms.
