Marvin (a beetle) and his friend James (a boy) return in the second volume of the Masterpiece Adventures early chapter-book series, based on characters in Broach's Masterpiece (2008). Finally old enough to join their fathers when they go "collecting," scavenging the humans' apartment for reusable items (a lost button = a beetle-size table), Marvin and his annoying cousin Elaine are determined to discover treasures, and they do. But when Uncle Albert is seriously injured, only Marvin knows where to go for help. Kids will be fascinated by the tiny characters' adventures and their creative repurposing of items, just as earlier readers enjoyed Mary Norton's The Borrowers (1952) and John Peterson's The Littles (1967). Broach strikes just the right tone in the dialogue and narrative, giving the beetles distinct personalities and dilemmas but always returning to the interspecies friendship at the heart of the series. Though not seen for review, the finished art will be two-color pen-and-ink pictures, as in the first volume, The Miniature World of Marvin & James (2014). Wonderful fare for transitional readers.
