Children's ✦ Penny’s Take
Walls Within Walls
Maureen Sherry · 2010
84/100
👍 Worth It
Four siblings solving a puzzle hidden inside the walls of a historic Manhattan apartment, with real New York architectural history woven through the clues — this is middle-grade mystery done right. A Kirkus star, a Texas Bluebonnet Award, and ALA recognition all point the same direction. Fans of Chasing Vermeer will find this delivers a similar thrill, with four capable protagonists working together instead of going it alone.
