Our view
“Mr. Penumbra’s 24-Hour Bookstore” is a light, good-natured mystery, full of affection for old books and new technology. Some find the constant presence of Google dated and the narrator too bland to carry the puzzle. It suits readers after a breezy, low-stakes adventure rather than a tense conspiracy thriller.
