This book is a behemoth, a veritable tour de force of the age he is portraying and that (I believe) is the books greatest strength and greatest weakness.
The Last Witchfinder is very difficult to classify or sum up in a sentence as it spans such a wide and varied time in both the settings that uses and the characters that are described, however I will do my best to do just that. The story centres on Jennet Sterne, a gifted and arguable petulant child whom is the daughter of Walter Sterne, the Witchfinder of Mercia and East Anglia, and sister to Dunstan, air apparent to Walter's title. As Dunstan is often away with his father learning the family trade Jennet is left with her Aunt Isobel, a scholar who opens Jennet's mind to the many wonders of the world. However, in this turbulent time a woman studying science and who lives alone with very quickly attract very unwelcome attention of Mr Sterne senior...
This is how the book begins, however in terms of describing the setting of the book I am doing it scant justice as the story takes us to Philadelphia, an Indian village, a desert island, to passionate embraces with her suitors and onwards to the challenge of parenthood. All of these settings are well described and the supporting cast are well defined but this is where I feel there is a weakness. Due to the volume of major characters and major settings you feel that the book is trying to cram in just too much for its 500 odd pages and on top of this I feel the timing / pacing of the book is also askew, for example there are many instances when you will be reading a passage to have it finish with (or the next passage begin with) and 4 years later, or Ben and Jennet went through 3 summers like this... This to me is a slightly lazy way around the narrative.
Now the really unusual part of this book is the interspersed narrative of Newton's Principia Mathematica, the idea being that the book (as with others) has a sentient nature, capable of having a one sided relationship with its readers and its author. I loved the concept but it felt just so out of place within this novel I struggled to see its relevance at all!
I would recommend this book but don't take it on lightly, it really needs sticking at. There is some wonderful interplay between the central characters which is worth the read alone but parts are overly wordy, not that relevant and can touch on the boring, thankfully the good parts far outweigh the bad.
