Books-A-Million, the nation’s second-largest bookstore chain, has appointed Courtney Adair as general counsel, replacing Tyler Novak, who’d been legal chief for more than a dozen years.

Adair comes to the 200-store chain from Chicago-based Excelon, the nation’s largest utility, where she was assistant general counsel for 28 months. Before that, she spent a total of 13 years at the law firms Greensfelder, Hemker & Gale and McKnight, Kitzinger & Pravdic.
