The Shark's Tooth is a poetic tale of imagination and conservation in which a young girl visiting her grandparents' beach house finds friendship with the ocean's creatures. Sharks' teeth are given to her by her new aquatic friends as gifts, symbolic of her connections to nature and the sea. As the little girl grows up and moves away to the city, she loses her kinship to the natural world. When she returns to the beach house as an adult, she is convinced that her childhood memories were only acts of make-believe—until she receives a sign that her ocean adventures may have been real after all.

The Shark's Tooth is the first children's book written by New York Times best-selling author Ron Rash. Cecile L. K. Martin's colorful cut-paper illustrations complement the story, and novelist and children's author Mary Alice Monroe provides an engaging afterword on the story's empowering message of creativity and conservation.
