The second book in Clark's trilogy reads very similar to the first in terms of tone and style. That's obviously not a bad thing for a trilogy! This time around though the central characters are Newton, Hooke, Halley, Wren and several others. Theirs is the time that picks up on Galileo and Kepler's findings, which were traced in the first book, and they find themselves equally embroiled in religion and power games. The obsession with gravity leads these men to ranks of power, but it's not an easy ride and they're constantly challenged by the monarchy and the church.
Once again, Clark does an admirable job creating the space and time of the book in vivid detail. This time around London and Cambridge take centre stage as the Royal Society is at the heart of the new findings. All the side characters and plots add to the story to make it more of a novel about these men rather than just their scientific discoveries, but I felt that these side-plots were too quickly told and discarded at times. They did not necessarily contribute to the overall character or story development so I felt like Clark felt obliged to include them from a biographical perspective. Having said that, they did surprise me most times as I never knew much about these men besides what they've contributed to science and astronomy.
Overall, it's a great follow-up to the first book and deserves a read if you enjoyed it.
