Christopher Ryan Grant i.e the narrator of the book is also a powerful force in the story. The narrator possesses such a voice that it can make us believe in everything which is happening in the story. We will never want to come out of this fantasy world after entering it the first time. Wayward Galaxy 3 and Last Contact had strong characterization and plot.
This one is strong in its theme but the characterization cannot be ignored as well. Each character of this strange army has its own story which is heart touching. The leader is also an exemplary figure for everyone who stands against the test of time quite strongly.
