Intrigue and danger threaten two Renaissance astronomers in this historical novel of Galileo, Kepler, and their quest to understand the universe. At the dawn of the 17th century, it was believed that the Sun revolved around the Earth. Yet some men knew that the Heavens did not move as they should. They began to believe exactly the opposite, a heresy punishable by being burned alive. The Sky's Dark Labyrinth follows the stories of Johannes Kepler and Galileo Galilei-two men of science who pursue the light of truth into dark and dangerous territory. Kepler, a German Lutheran, was the first man to demonstrate how stars and planets moved according to mathematical laws. Galileo, an Italian Catholic, tries to claim Kepler's success for his own Church. Both men are soon enmeshed in a web of intrigue orchestrated by forces within the Vatican itself. The Sky's Dark Labyrinth is the first novel in a trilogy that explores the personal and professional struggles of these iconic figures.
