Andrew Garfield played the title character in Channel 4's adaptation
Boy A, a controversial novel about a child offender, has been voted best "book to talk about" in a public poll organised as part of World Book Day.
Author Jonathan Trigell, who receives a £5,000 prize, said he was "delighted" to win the award voted for by readers.
"I always hoped Boy A would be a book people enjoyed talking about," he said.
The book, published in 2004, tells of the release of a 24-year-old who has spent most of his life in institutions after committing a childhood crime.
The book was recently filmed by Channel 4, starring Andrew Garfield as the title character and Peter Mullan as his social worker.
