October is the time to meet a famous author at the Evanston Public Library.  Three widely acclaimed, culturally provocative writers will be discussing and signing their work and greeting fans at EPL.

On Oct. 2, 7-9 p.m. in the Community Room of the Main Library, 1703 Orrington Ave., young adult (YA) novelist Maggie Stiefvater, author of such genre-bending works as “The Books of Faerie,” will talk. Throughout her works, Ms. Stiefvater blends fantasy, Celtic myth and romance to create vibrant worlds and characters.

At her EPL appearance, the author will talk about writing, introduce her new book, “The Raven,” answer questions and sign books.

A very different writer will appear at 4 p.m. on Oct. 3 in the Main Library Community Meeting Room. Feminist social critic Naomi Wolf will discuss and sign her latest work, “Vagina: A New Biography.”

Ms. Wolf is the author of eight books. In 1990 she jump-started the “third wave” feminist movement with “The Beauty Myth,” which was named one of the 70 most influential books of the 20th century by The New York Times. In her latest work, “Vagina a History,” Ms. Wolf states that the way a culture views and treats the vagina demonstrates how much respect the society has for all women.

The third October author is Cory Doctorow, a science fiction writer, blogger, and digital rights activist. His award-winning adult and YA novels have been translated into dozens of languages. Reviewers note that Mr. Doctorow has “appeared at the vanguard of a trend within science fiction that’s so bleeding-edge it doesn’t even have a stupid nickname yet.”

 At 7 p.m. on Oct. 11 at the Main Library, he will be reading from his latest novel, “Pirate Cinema,” a dystopian sci-fi thriller, taking questions and signing books.

Authors who present startling new ideas, as these three do, are often banned or challenged for their politics, descriptions of sexuality or perceived lack of patriotism.  In October EPL welcomes them and features “Books on the Chopping Block,” a Banned Books program.

At 3 p.m. on Oct. 6 at Fleetwood-Jourdain, 1655 Foster St., City Lit Theater will present a series of dramatic readings from the top 10 most frequently challenged  or banned books of 2011. Among the works is “The Hunger Games” trilogy by Suzanne Collins. Discussion will follow.
