It is a tale of two cities - the legendary duel between haughty, democratic Athens and brutal, unbeaten Sparta. After seven years of bloody conflict, a barren island in a remote corner of Greece becomes the stage for what promises to become a second Thermopylae. Four hundred Spartan soldiers are cut off by enemy ships on a narrow strip of land, starving, without supplies, yet sworn to uphold their indomitable heritage. Meanwhile, all around them, the powerful Athenian Navy masses for the inevitable assault. 

As the war of nerves wears on, Spartan nobles and Athenian demagogues maneuver in the background - and two estranged Spartan brothers serve together for the first time. The eldest, Antalcidas, is a legendary warrior hobbled by a damaging secret. His brother Epitadas is envied, popular, and cruel. Together they must overcome a lifetime of hostility to survive the battle of their lives. 

"With The Isle of Stone, Nicholas Nicastro joins the illustrious pedigree of Mary Renault, Valerio Massimo Manfredi and Steven Pressfield with great style and enormous panache. His hero's checkered life story is used to frame a dark and darkening history of Sparta between a hugely destructive natural disaster, a great earthquake in 464 BC, and a self-inflicted, man-made debacle during the prolonged and even more destructive Peloponnesian War. Nicastro knows his ancient sources intimately, but also has the born novelist's instinct to flesh out their bare bones all too plausibly. Nicastro's antiheroes of the isle of Sphacteria are the dark side of Pressfield's heroes in Gates of Fire. Both demand and repay the attention of all lovers of expert historical fiction."
