Lord Kalvan of Otherwhen

The Paratime Police patrolled the vast number of alternate time dimensions. Their aim was to keep the existence of the alternative Earths a secret and prevent these Earths from mixing and destroying each other.\nBut the Time Police made mistakes, and they made a big one when a seemingly ordinary Pennsylvania State Trooper named Calvin Morrison was accidentally switched into the Aryan-Transpacific sector, Styphon's House subsector.\nIn just a few weeks, Morrison was being hailed as Lord Kalvan, and was masterminding a campaign that could blow the whole Paratime secret sky high!
