Stone Circles

In each of the books in this series, a mystery is described, and the case for and against a rational scientific explanation is put forward.

Evidence is provided in the form of eyewitness accounts and written and pictorial reports.

Whilst there may not be a scientific explanation for each phenomenon, the books do not attempt to reduce the mystique of each one, but instead offer a variety of possibilities to allow readers to come to their own conclusions. Recurrent themes within the series are: scientific developments and techniques used to examine evidence; links between science and natural phenomena; materials and processes used to create and expose fake evidence.
