The Unnameables

Medford lives on a neat, orderly island called—simply—Island.
Islanders like names that say exactly what a thing (or a person) is or does. Medford Runyuin is different. A foundling, he has a meaningless name that is just one of many reminders that he’s an outsider. He also has a secret that could get him banished from Island forever.
A strange creature is about to arrive on Island, and Medford’s secret will be out before he can blink twice.
