" Both more ambitious and less satisfying than its predecessor, 'A Princess of Mars,' John Carter's return to Barsoom relies far too much on coincidence to move its plot along. Still an entertaining and inventive read, 'The Gods of Mars,' it should be noted, is also the first part of what is really a double novel, with the action concluding in 'The Warlord of Mars.' The book does feel, well, over-crowded. Too many wanderings through tunnels! "
