Twilight is upon us.

The latest movie in the wildly popular vampire series, Breaking Dawn: Part 1, makes its much-awaited debut tonight. Eager fans have camped out throughout the country in anticipation of its release. Now, the Oak Bluffs library is getting in on the action too.

The library is hosting a release party “prom” from 3:30 to 5:45 p.m., featuring all things Twilight: trivia games, videos, a photo shoot with an Edward Cullen cardboard cutout and, of course, prizes and food. Ages 12 and up are in invited to the prom. For more information on the free event, call 508-693-9433.

Breaking Dawn will screen at Entertainment Cinemas in Edgartown tonight at 4 p.m., 6:45 p.m. and 9:20 p.m.
