If you're determined to enjoy every last moment in the remaining weeks of the waning summer, go right ahead. But it wouldn't hurt to look into the future a little bit.

Fall is coming, and even as the last few summer festivals get crossed off the calendar, the annual autumn celebrations we all know and love are getting closer every day. Whether you want food, wine, films, books or live music, you'll find it all in Sonoma County in September.

Here's a quick look at next month's upcoming perennial favorites:

<strong>Sept. 21 — Sonoma County Book Festival.</strong> The county's annual salute to the literary arts moves this year from Santa Rosa's Old Courthouse Square to the Santa Rosa Junior College campus.

Novelists lined up for the event include Dorothy Allison, author of the celebrated family saga "Bastard Out of Carolina," and Helene Wecker, who won national attention with her debut, "The Golem and the Jinni," about supernatural creatures in turn-of-the-century New York.

Hours are 10 a.m.- 4 p.m. The festival will feature speakers, panels, exhibitors, poetry, workshops and activities for children at the Bertolini Student Center and Quad at the college, 1501 Mendocino Ave. Admission and parking are free for this event. <a href="http://socobookfest.org" target="_blank">socobookfest.org</a>
