Which Narnia book by C.S. Lewis features the voyage of the ship Dawn Treader?

The Voyage of the Dawn Treader is the C.S. Lewis Narnia book featuring the ship Dawn Treader.

Published in 1952, the novel follows Edmund and Lucy Pevensie after they return to Narnia with their cousin Eustace Scrubb. They join King Caspian aboard the Dawn Treader, which is searching for seven lords who were banished from Narnia by Caspian’s uncle, Miraz.
