I have loved this series since I was a teenager. My mom and dad read the series and recommended it to me. I\'ve read the whole series at least 7 times. By the way, the Princess of Mars is a 3 book continuation. The Gods of Mars is the second book and Warlord of Mars is the 3rd. However, there is 11 books to the whole series. Edgar Rice Burroughs is a great author and the tarzan series is just as fun.
