"I am delighted and honoured. This book took me ten years to research and write and, despite the fact that it weighs 8lbs and costs £95, has proved surprisingly popular with collectors and students of British Iron Age coins".

"A unique work of reference will always sell well if it meets a need, if it's comprehensive and authoritative, and if it's well illustrated. John's Divided Kingdoms catalogues more than 10,000 Celtic gold coins of the southern, north Thames and Kent regions, is the first book that pulls together the past 50 years of coin finds to reconstruct the lost political history of southern Britain between Caesar and Claudius, and illustrates 600 of the coins with twice-size photos. I'm thrilled that Divided Kingdoms has been publicly acclaimed by the British Numismatic Society. In 2018 it was highly commended in the competition for the prestigious IAPN Book Prize."
