The final chapter in the miserable, unfortunate tale Mr. Lemony Snickett keeps begging us, in his own volumes, to not read! For to do so would be to make one's self most miserable, which is unfortunate for the reader.
Anyways, the three orphans find themselves castaways on an island after their boat is wrecked in a terrible storm. The island is inhabited by other castaways who have come to form a community with a specific culture and rules, and Count Olaf quickly angers the hosts and is ostracized.
The Baudelaires too grow uncomfortable with the stifling rules of the island. Upon uncovering the truth - their parents were the original castaways and leaders - the Baudelaires accidentally start a civil war that leads to the death of every inhabitant except the current leader, Captain Ahab (nice Moby Dick references throughout the book).
A bittersweet ending, Count Olaf dies with the rest of the islanders, and the Baudelaire orphans are now the surrogate parents of another orphan whose mother, a friend of the Baudelaire's who aided them in their quest, dies during childbirth and from poisoning simultaneously.
It is on this island, alone, that the Baudelaires and their surrogate child spend the rest of their known days.
The series started off strongly, the first few novels gripping the imagination and bringing to life a compelling villain. The middle of the series (books 6-8 specifically) are dreadfully dull and predictable. Snickett recaptures his earlier genius throughout the last five books and takes the reader on a great number of exotic adventures and delivers an unexpected, if not completely unfortunate, ending.
