It's that time again: the Brooklyn Book Festival is upon us, and every tote-bag-toting, horn-rimmed glasses-wearing reader and writer in the city will be there. The festival takes over a full three days, from September 15 through 18, but not even a die-hard bibliophile could see all there is to see, so here are a few highlights.

All events at the Festival are free, but the events in the Borough Hall Courtroom (209 Joralemon Street) and St. Francis College Auditorium require tickets, which are distributed an hour ahead of time at information booths dotting the Borough Hall Plaza. Almost all of the big-name events take place on the 18th. There's always a lot to see, but get there early and stay focused: you don't want to miss Jhumpa Lahiri because you're browsing used paperbacks, do you? Here's your hour-by-hour breakdown.

Words and Sounds:Mary Karr (Lit: A Memoir) and Nelson George (The Plot Against Hip Hop) discuss their most recent books, along with the role that music plays in their creative process.

Unholy Paths to Redemption: Pulitzer Prize winning author (and Gothamist favorite) Jennifer Egan (A Visit from the Goon Squad), James Hannaham (God Says No) and John Burnham Schwartz (Northwest Corner) look at the alternative routes their characters take to lose themselves—jeopardizing work, family, and love—to find themselves again.
