The following book is a history of Dominica. Today, it is officially known as the Commonwealth of Dominica, an island country in the Caribbean. Dominica has been nicknamed the "Nature Island of the Caribbean" for its natural environment. It is the youngest island in the Lesser Antilles, and in fact it is still being formed by geothermal-volcanic activity, as evidenced by the world's second-largest hot spring, called Boiling Lake. The island has lush mountainous rainforests, and it is the home of many rare plants, animals, and bird species.
