Bonaventure - Three Years on the Island

In my first novel of the Omega Chronicles, "OMEGA - The Lost City of Altinova," the story failed to discuss the adventurer's first three years on the island until they discovered the mystery around so many different things that happened that couldn't be explained.
In this book, Book 2 of the series, we discuss their first three years of abandonment. This novel written four years later is actually the prequel to Omega - The Lost City of Altinova.
