Kanti Cycle 2: Small World

Top review on Amazon:

This book is an excellent sequel! It has the same overall feel as the first book but has a fresh new environment and new challenges that come along with this environment. This book is one of the best books I have read recently. The story takes place in a unique Sci-Fi world where the main species, Geroo, have been forced to move into space due to overpopulation. This book deals with life aboard a space ship and the struggles that come with it. Overall, it is a great Sci-Fi book with mystery and plot twists that are unexpected but not absurd.
