Allison K. Hymas

Allison K. Hymas writes middle-grade mysteries and adventures in which young characters solve problems through observation, codes, and uneasy cooperation. Secrets of Stone and Sea follows twelve-year-old twins Peter and Kai after they accidentally awaken an ancient sea god and must uncover links among myth, language, Atlantis, and their own family. Macmillan published the novel through Roaring Brook Press and identifies its layered puzzles and coastal Massachusetts setting. Kirkus independently highlights the embedded ciphers, opposing sea-and-land imagery, and family-centered quest, classifying it as fantasy for readers aged eight to twelve. Hymas's earlier novels, including Under Locker and Key and The Explorer’s Code, likewise use clues and mysteries to move their young casts into action. Secrets of Stone and Sea expands that puzzle-minded approach into mythic fantasy without losing the practical work of decoding evidence. Readers can expect an adventure where contrasting twins bring different strengths to a problem that neither could solve alone.
