Masterpiece is a middle-grade mystery about stolen art, miniature worlds, and the surprising friendship between a talented beetle, Marvin, and a lonely eleven-year-old boy named James.

When James receives a pen-and-ink set for his birthday, Marvin discovers that he can create tiny, intricately detailed scenes by dipping his front legs in the cap of ink and drawing on paper.

James is mistakenly credited with Marvin's amazing pictures, and soon the beetle and boy are swept up in an adventure at the Metropolitan Museum of Art that involves masterpieces, forgeries, and a stolen pen-and-ink drawing by the great Renaissance artist Albrecht Dürer, which Marvin and James are determined to recover.

Basil E. Frankweiler, and Charlotte's Web, this novel explores friendship, sacrifice, and moral dilemmas in the context of a high-stakes art heist.
