Secret Seahorse

Aquatic adventure abounds in the gently rhyming Secret Seahorses by Stella Blackstone, illus. by Clare Beaton. Readers can look for evidence of the seahorse that hides on each exquisitely stitched, then photographed, spread. An undersea landscape assembled from fabrics, beads, buttons and sequins are home to jellyfish made of lace, fringe anemones and a mermaid bedecked with beads. A visual glossary helps readers identify and learn about these creatures of the deep. (Mar.)
