While fall is partly about harvests and Oktoberfests, it’s also book-release season. At the annual Twin Cities Book Festival you can pick up items on your reading list, shop for holiday gifts, and meet with authors of every writing style and genre. Highlights from the generous schedule of readings include Daniel Handler, whose sex-fueled All the Dirty Parts revels in the world of a teen horndog; Alex Lemon, who has returned with a dark new memoir chronicling his health struggles and reflecting on haunting moments from his childhood; and Sen. Al Franken, who will be talking politics with his signature sharp wit. Duluth publisher Holy Cow! will be turning 40 with a birthday party and a reading from its literary all-stars, and teens and kids can find fun things to do and see in special sections just for them. Things kick off Friday night with an opening reception featuring appetizers, drinks, and an author talk with John Freeman, Claire Vaye Watkins, and Lawrence Joseph (admission is $25 for the party, but it’s free to attend the author talk). The big free festival we know and love is all day on Saturday. More info can be found at www.raintaxi.com/twin-cities-book-festival.
