I was very pleased to read this review of The Sky's Dark Labyrinth on the Australian website Media and Culture Reviews. Reviewer Tony Williams says:

"Through Clark's vivid blend of fact and informed fiction, we are given insights into the struggles of Kepler and Galileo against the Vatican and the repercussions that their findings had on their families and society."

The Sky's Dark Labyrinth is available in Australia here.
The Sensorium of God is also available in Australia here.

You can read the full review here.

Thank you Tony.
