"An epic tale of murder, treachery, bravery, and love In 1524, in what is now Germany, hundreds of thousands of peasants revolted against the harsh treatment of their aristocratic overlords. Agnes is the daughter of one of these overlords, but she is not a typical sixteenth-century girl, refusing to wear dresses and spending more time with her pet falcon than potential suitors. There is only one suitor she is interested in: Mathis, a childhood friend who she can never marry due to his low birth status. But when a rogue knight attacks Agnes and Mathis shoots the knight to save her, the two are forced to go on the run together, into the midst of the raging Peasants' War. Over the next two years, as Agnes and Mathis travel the countryside, they are each captured by and escape from various factions of the war, participate in massive battles, make new friends both noble and peasant, and fall in love. Meanwhile, Agnes's falcon finds a mysterious ring, and Agnes begins having strange, but seemingly meaningful dreams. Dreams that lead the two lovers to revelations about their place in the world and in the emerging German states. With The Castle of Kings, Oliver Potzsch has written a historical yarn that calls to mind Ken Follett's The Pillars of the Earth and Bernard Cornwell's Agincourt."--
