Mayor Thomas Menino on Thursday will swear in author Dennis Lehane, a Dorchester native, as a member of the Boston Public Library’s board of trustees.
The swearing-in is set for 4:30 p.m. in the mayor’s City Hall office, according to Menino’s schedule.
Lehane, a former St. Margaret’s altar boy  who grew up on Hinkley St., has written a number of bestsellers, including “Mystic River,” “Shutter Island” and “Gone, Baby, Gone.” The aforementioned novels have been turned into films.
Lehane will replace James Carroll, who left the mayorally-appointed board  in May. Past authors on the nine-member board included historians Doris Kearns Goodwin and David McCullough.
According to Lehane’s website, he and his wife Angie split their time between Boston and Florida.
Lehane’s website also notes, “Before becoming a full-time writer, Mr. Lehane worked as a counselor with mentally handicapped and abused children, waited tables, parked cars, drove limos, worked in bookstores, and loaded tractor-trailers. His one regret is that no one ever gave him a chance to tend bar.”
