In 8th century Mercia, King Offa lusts for power. His queen, Cynethryth, is an ambitious politician minting her own coins – a first for any woman in the male-dominated era.

Amid societal changes, the two navigate power struggles, revolts and alliances in the tumultuous Anglo-Saxon Britain, leaving their mark during a pivotal time in English history.

But where is Offa's place among the English kings, and who is the real force in his reign? There is little concrete evidence, but in OFFA - REX MERCIORUM, John Broughton breaks through the veil of time and provides an entertaining, well-researched historical tale.
