This 40 page mid-size softcover presents readers with to looks at life on the US/Mexican border: the first, "A Night on the Border'" is set in Nogales, a city through which the border runs, with its northern half located in Arizona, and its southern half in Sonora; the second, "A Day on the Border," is set in the desert terrain of southern Arizona, along which the border wall – the "scar" of the title – runs for 262 miles, before petering out in the middle of nowhere. 

Written by Andrea Ferris, who also supplies an Author's Note, and illustrated by Renato Chiocca in detailed soft pencil renditions.
