Ken Follett is one of my favourite authors - his epic "Pillars of the Earth" is probably the one work of fiction I enjoyed the most.
This book is a rather different kind of book in several ways - the story is considerably shorter, and thus it won't take you long to read it. There is also less of the lush descriptive detail that makes some of his other books so immersive. Despite this, there is still a very intricate plot, involving many quirky characters with outrageous backgrounds, and there is a sense of dry humour sprinkled throughout.
I did enjoy the book, but I can't say I enjoyed it as much as I did some of his others. I found myself getting characters mixed up, and several times I had to turn back to an earlier page to try and find that missed detail.
It seems appropriate, then, that the author himself should have said in his foreword, "Clever plots satisfy authors more than readers." As a writer I would have been proud of writing "Paper Money", but admittedly it's not one of the first books I would pick up on a cold winter evening by the fireplace.
