Participating authors include Katherine Howe, a New England-based historical novelist with a keen imagination; Kambri Crews, whose debut memoir, Burn Down the Ground, is getting strong notices; and David Bell, a Cincinnati native whose first novel, last year’s Cemetery Girl, was a creepy, deftly crafted thriller. That, of course, is just a tiny sliver of those who’ll be on hand. Perhaps best of all: Books by the Banks is free and open to anyone who wants to experience its many pleasures.
