Late 1799: Napoleon Bonaparte seizes power in Paris as an Ottoman army of 80,000 descends upon Egypt. Abandoned, French general Kléber wants to get his soldiers home, their only hope a rescue fleet led by the deadly 74-gun Généreux. For William John Hazzard and the marines of 9 Company the order is clear: find the Généreux.
On the hunt with De la Vega and the Volpone, they meet fire and battle amid the terrors of the Ionian Gyre and the Deeps of Hades. Beset by spies from Istanbul to Toulon, Hazzard races after the Généreux and the desperate French convoy – and brings Nelson out from Palermo to give battle once again.
