It’s a magical time for book lovers: Oct. 23-24 marks the annual Boston Book Festival. This year’s kickoff keynote will be given by Margaret Atwood, the award-winning Canadian novelist and poet known for such groundbreaking works as “The Blind Assassin” (recipient of the Man Booker Prize) and “The Handmaid’s Tale.” Atwood is currently touring in support of her latest book, “The Heart Goes Last.” She and writer Kelly Link will chat about the future of fiction, and Atwood will sign books. Just one catch: Advance tickets are sold out. They’re still available, though, if you become a Boston Book Festival member at the Bibliophile level ($150) or above. Each membership also comes with a goodie bag. Atwood’s talk is at 7:30 p.m. on Oct. 23. Old South Sanctuary, 645 Boylston St., Boston, 617-945-9552, www.bostonbookfest.orgKara Baskin can be reached at email@example.com.
