Stephen Elliott is a 21st-century Renaissance man: a novelist (Happy Baby, from McSweeney's, is the best time-twisty character study since Martin Amis's Time's Arrow), memoirist and erotic writer (My Girlfriend Comes to the City and Beats Me Up), and the editor of an always-entertaining, literary-minded blog, the Rumpus. His newest book, The Adderall Diaries, combines all Elliott's specialties into one mad explosion of a book. It's a thrilling mix of memoir, true crime, sadomasochism, drug use, and boxing, and his most exciting book yet by far. (Elliott Bay Book Company, 101 S Main St, 624-6600. 7:30 pm, free.)
