A Red Sun Also Rises

the long version

"Reclusive Anglican priest Aiden Fleisher and brilliant hunchback Clarissa Stark travel as missionaries to the distant South Pacific island of Koluwai, where they encounter hostile natives--and a gateway to another world lit by two suns. Fleisher and Stark meet the native Yatsill, consummate mimics who construct an elaborate society based on Victorian London, using details mined from the thoughts of their new visitors. As Aiden and Clarissa strive to make sense of this strange new world, they become aware of an approaching menace: the arrival of a third sun that will bring the Blood Gods to ravage the world."--Library Journal.
