The Unbreakable Code

(3) 4-6 Illustrated by Sarah Watts. When their teacher, Mr. Quisling, begins a furtive book quest that results in fires around San Francisco, puzzle aficionados Emily and James (Book Scavenger) try to discover who's setting the fires, while simultaneously solving a Mark Twain–related "unbreakable code" to find treasure. Cryptographers and mystery lovers will enjoy following the clues as the smart plot and whom-to-trust character development keeps readers guessing.
