Two Years' Vacation (French: Deux ans de vacances) is an adventure novel by Jules Verne, published in 1888. The story tells of the fortunes of a group of schoolboys stranded on a deserted island in the South Pacific, and of their struggles to overcome adversity. In his preface to the book, Verne explains that his goals were to create a Robinson Crusoe-like environment for children, and to show the world what the intelligence and bravery of a child was capable of when put to the test.
As with most of Verne's works, it was serialised (in twenty-four parts between January and December 1888) in the "Extraordinary Journeys" section of the French Magasin d’Éducation et de Récréation by Parisian publisher Hetzel. It was also published in book form in two volumes in June and early November of that year. An illustrated double volume with a colour map and a preface by Verne was released in late November.

Plot summary 
The story starts with a group of schoolboys aged between eight and Fourteen on board a schooner moored at Auckland, New Zealand, and preparing to set off on a six-week vacation. With the exception of the oldest boy Gordon, an American, and Briant and Jack, two French brothers, all the boys are British.
While the schooner's crew are ashore, the moorings are cast off under unknown circumstances and the ship drifts to sea, where it is caught by a storm. Twenty-two days later, the boys find themselves cast upon the shore of an uncharted island, which they name "Chairman Island." They go on many adventures and even catch wild animals while trying to survive. They remain there for the next two years until a passing ship sinks in the close vicinity of the island. The ship had been taken over by mutineers, intent on trafficking weapons, alcohol, and drugs. With the aid of two of the surviving members of the original crew, the boys are able to defeat the mutineers and make their escape from the island, which they find out is close to the Chilean coast (Hanover-Island located at 50°56’ S, 74°47’ W).
The struggles for survival and dominance amongst the boys were to be echoed in William Golding's Lord of the Flies, written some 66 years later.
