The literature lovers at Writers & Books welcome readers to revel and mingle in costumes inspired by their favorite character at the store's annual masquerade. From 8 p.m. to midnight, partygoers of all ages can enjoy a ball with a literary twist that doesn't end in being turned back into a pumpkin carved in the likeness of Mr. Hyde. To prepare for the bash, party planners deck each room in the store?a historic former police precinct building?in the trappings of a genre such as horror, sci-fi, romance, fairytale, or mystery. In addition to macabre games and readings, the spooky soiree will feature raffles and a spirited costume contest. Attendees should bring cash for drinks, raffle tickets, and tipping the scurrying, disembodied hand that mixes the cocktails.
