Two intriguing historical tales packaged together! "To Be First" follows two space voyagers from an alternate universe as they return from the moon, in 1933. In their timeline, manned rocketry began in the Ottoman Empire, which advanced and spread. When these Ottoman lunanauts end up orbiting our comparatively backward world, they have a choice to make, one that will forever change their future and ours. In "Wheels of Heaven," an arrogant Roman astrologer finds a geared Grecian machine for predicting the positions of celestial bodies. On the voyage back to Rome, he meets a sailor who dismisses astrology, an astonishing notion in 86 B.C. But when the sailor's prediction is right, and every one of the astrologers is wrong, he must question his most basic beliefs.
