This is a really sweet middle-grade book, with its wintery, frolicky adventures and cute illustrations. The perfect escapism! Plus the heroin is into word enigmas - she's a champion of word ladders - and the readers are encouraged to unravel the mystery alongside her. The light touch of magic was well incorporated, and the lovely friendship blossoming between Elizabeth and a young inventor was a pleasure to follow. Bonus points for a swoon-worthy library and full-page illustrations.
