The main character is a Nicoleño girl named Karana. She has a brother named Ramo and an older sister named Ulape. Her people live in a village called Ghalas-at and the tribe survives by gathering roots and fishing and hunting. One day, a ship of
Russian fur hunters and their
Creole and
Aleut workers led by Captain Orlov arrive and persuade the Nicoleños to let them hunt
sea otter in exchange for other goods. However, the Russians attempt to swindle the islanders by leaving without paying. When they are confronted by Karana's father,
Chief Chowig, a battle breaks out. Karana's father and many other men in the tribe die in battle against the well-armed Russians. Later, the "replacement" Chief Kimki leaves the island on a canoe for new land in the East. Eventually, he sends a "giant canoe" to bring his people to the mainland even though Kimki himself does not return. The white missionaries come to Karana's village and tell them to pack their goods and go to the ship. Karana's brother, Ramo, runs off to retrieve his fishing spear. Although Karana urges the captain to wait for Ramo to return, the ship must leave before a storm approaches. Despite restraint, Karana jumps off the ship and swims to shore, and the ship departs without them. While awaiting the return of the ship, Ramo is brutally killed by a pack of
feral dogs. Alone on the island, Karana takes on everyone's tasks, such as hunting, making
spears, and building
canoes to survive. She vows to avenge Ramo's death and kills several dogs, but has a change of heart after wounding the leader of the pack. Karana tames him and names him Rontu. Over time, Karana makes a life for herself, even successfully hunting a giant devilfish (a massive creature like an octopus or squid) with Rontu. She builds a home made of
whale bones and stocks a cave with provisions in case the Aleuts come back, so she can hide from them. Karana also tames some
birds and an otter, named Mon-a-nee, while feeling a close kinship to the animals (the only inhabitants of the island beside herself). The Aleuts return one summer, and Karana takes refuge in the cave. She observes the Aleuts closely and realizes that a girl named Tutok takes care of the domestic duties including getting water from the pool near Karana's cave. Fearful of being discovered, Karana goes out only at night, yet the curious girl stalks Karana, and the two meet. Karana and Tutok exchange gifts and Karana realizes how lonely she has been. The next day, Karana sees the ship with Tutok departing before Karana returns to her house and starts rebuilding. More time passes, and Rontu dies. Karana soon finds a young dog that looks like Rontu and takes him in, naming him Rontu-Aru. One day, Karana sees the sails of a ship, but it moors offshore and leaves. Two years later in the spring, the boat returns. Karana dresses in her finest attire, a dress of
cormorant feathers, and waits on the shore for the boat. Her rescuers make a dress for her, as they believe Karana's dress of cormorant feathers is not appropriate for the mainland. She does not like the dress, but realizes that it is part of her new life. The ship takes Karana, Rontu-Aru, and her two birds to the
mission in
Santa Barbara,
California. There, Father Gonzales tells her that the ship that had taken her tribe away had sunk before it could return to the Island of the Blue Dolphins for her. ==Publication==
