Fleetway's revenge (a Scourge and the secret door sequel)

Ten years after Sonic and Scourge's honeymoon, Fiona and Rouge, Scourge's practical sisters, disappear. With his new advisor Amy still in denial of Scourge's first adventure and Sonic away on business, that just leaves Scourge's eight year old daughter, Serena, to help him. Will Scourge be able to repay his sisters for saving him a decade ago, or will Fleetway the demon hedgehog get his revenge?

(Author's note: I am going to publish every chapter twice, once in normal point of view and once in Serena's Princess Log)
