Celebrate Small Business Saturday at the San Francisco Ferry Building, where Paul Madonna will be hosting a meet and greet in conjunction with his recently released novel, “Close Enough for the Angels.” Madonna is a Bay Area darling, due in part to his long-standing comic series “All Over Coffee,” which ran in The Chronicle for 12 years. “Close Enough for the Angels” (from Petty Curse Books) incorporates more than 100 rich drawings, which bring a haunting visual element to a story of a mysterious disappearance and a former celebrity’s unwilling return to the limelight. Discuss “Close Enough for the Angels” with Madonna at 11 a.m.
