AD 381. Five years have gone by since a Roman governor ordered the deaths of a Gothic king and his attendants at a feast in their honour. This disastrous act led to warfare in the Roman Empire and the death of the Emperor Valens. Now, the Empire is calm once more, but for the eight legionaries who committed the killings, the bloodshed is only just beginning. Fritigern, brother of the murdered king, has sworn revenge on his brother’s killers. Now king of a powerful Gothic tribe, he will not rest until the men are hunted down. Flavius Focalis is one of those legionaries. Surviving an attack at his villa, he realises the danger he and his family are in, and seeks to warn his former comrades, for he knows Fritigern will give them no quarter.
