The Sensorium of God: The Sky's Dark Labyrinth Trilogy: Book II — Stuart Clark

It's the mid-17th century and the mystery behind the movement of the planets -- elegantly described by Johannes Kepler almost a century earlier -- remains unsolved. Edmond Halley, adventurer, astronomer, and ladies' man, and reclusive alchemist and fearsome mathematician Isaac Newton become collaborators in the attempt to decipher this puzzle. Due to this simple partnership, the lives of both men are plunged into crisis, Europe is pushed headlong towards the Age of the Enlightenment, and science is catapulted into its next decisive clash with religion. Inspired by the key events in man's quest to understand the universe, this brilliant and gripping fictionalization brings historical characters to life.
