In the first of The Eye of Odin short prequels, Sarah Finn, a fifteen-year-old witch-for-hire, finds herself atop the Athenian Acropolis, exchanging money for an ancient Spartan helmet said to contain extraordinary powers. But when the exchange ends in a double-cross, it exposes a conspiracy that could reignite a two thousand-year-old war between Athens and Sparta, and keeping the peace will rest upon the shoulders of the scrappy, young witch.
