Winter 1795: Lieutenant John Pearce, reckoning to have finally ditched his old enemy, Admiral Hotham, has found a new one in Henry Digby, previously a friend. Meanwhile, Pearce's pregnant and recently widowed lover is adamant they cannot be seen together for the sake of their unborn child as she seeks respectability in society.

Aboard HMS Flirt as part of the squadron led by Horatio Nelson, Pearce and his Pelicans soon join a reconnaissance mission which results in the destruction of a key French battery—though the success is short-lived. In raids ashore, split loyalties, and bloody sea fights, Pearce must show bravery and resourcefulness to ensure his survival and return to Emily. But the headstrong lieutenant is faced with immense danger, not only from the enemy but also from his own captain. Only luck and Pearce's fierce appetite for battle can save them from the perils ahead.
