Island of the Blue Dolphins, by Scott O'Dell, was first published in 1960 and won the Newbery Medal in 1961. It has been enormously popular among young readers ages 9-12, as well as among teenagers and grown-ups. It is a fictional account of a real life Native American girl who lived during the first half of the 19th century on San Nicolas Island, the outermost of eight Channel Islands (off the California coast).
This girl spent many years living alone on the island. In the novel, she is surrounded by some huge, vicious, wild slobberdogs. She discovers that even wild, nasty slobberdogs are more bark than bite once you get to know them. She has to face other terrors, such as invading Aleutian sea otter hunters, who were responsible for driving her tribe from the island (when she was accidentally left behind).
This book is an exciting read, even if there are way too many slobberdogs and not any kitties, not even tigers or lions. The author really grabs your attention from the outset, and he keeps a fairly tight grip until you've reached the story's conclusion.
My only recommendation would have been this: more dolphins, fewer slobberdogs. Plus a couple dozen cats.
