Masterpiece

This is an award winning (well, not really, but still) book by Elise Broach. Marvin, the beetle, lives under the kitchen sink in Jame's house. For his birthday, James gets an ink set. Marvin sneaks on to his desk and draws an amazing view of the scene outside the window. Skipping some plot, Marvin is soon caught up in an art heist. Will this creature survive?
