Friends and neighbors in Portland, Maine, Susan Conley, a writer, and Winky Lewis, a photographer, often talked about collaborating, but as is often the case life kept getting in the way. Until they made their lives the very subject of their art. At the start of every week for 52 weeks Winky e-mailed Susan a photo she had snapped of one of their five respective children — who happen to be best friends — or of their street, or other places in Maine, and Susan would write mini-stories to accompany each. The result is an evocative portrayal of the simple pleasures of childhood and motherhood. “Stop Here, This Is the Place: A Year in Motherland,’’ by Susan Conley and Winky Lewis (Down East Books, 2016), $17.95.
