no you do not need to read all the other novels that crossover. although I was familiar with Robinson’s other novels I had not read them yet which gave me apprehension to read this without knowing the backstories. however the author does a great job quickly explaining in summarizing where all these new awesome characters come from and leaves it in a way where I want to read these other books. It has been an exciting end to the Nemesis Saga and as a Godzilla fan it’s been one of my favorite books and series since it came out.
