Celebrity historian Tom Holland's 2023 children's book (for 9yo+) The Wolf-Girl, the Greeks, and the Gods: A Tale of the Persian Wars works just as well for adults as a brief, simple, and engaging reimagining of the 5th Century Persian Wars against the Greeks, specifically the 480BC battle at Thermoplyae, where 300 Spartans fought and died resisting the Persians, thus providing time for the Athenians and their allies to regroup, and, under a brilliant naval strategy devised by their general Thermistocles, defeat and rout completely the superior forces of the Persians, a famous victory that not only saved the Greeks, but almost certainly rescued an infant Western civilization from threatened destruction, and enabled the flourishing that informs the West to this day.
Holland tells the story through the eyes of Gorgo, the historical Queen of Sparta, wife to King Leonidas who led the famous 300, and whose otherwise historically accurate account is spiced with imaginary interactions with many of the most well known mythical Greek gods keen to preserve their favoured people, and including some classical metamorphosing into spirited wolf animality to outrun and outwit the Persians.
The result is a thrilling tale even for adults. What today's kids will make of it I do not know, but it worked for me. And, of course, making a girl the main character in the retelling of this famous warrior story adds a commercially astute and subtle marketing edge suited to the gender fixation of our times.
