KS5/Adult LRC Book Recommendation - Now We Shall Be Entirely Free by Andrew Miller

Somerset , 1809: a ravaged soldier drags himself across the threshold of his home, destined to perish were it not the efforts of his housekeeper to save him. This is Captain John Lacroix, a combatant of the Peninsular War, a man shattered by something so unspeakable his only instinct is to flee from himself. With his healing comes command to return to his regiment: instead, Lacroix chooses the Hebrides.

Meanwhile, across the moors and fields follow his possible nemesis: the English corporal Calley and a Spanish officer by the name of Medina, under secret orders. An atrocity was committed on the British retreat to Corunna, and justice must be delivered. Lacroix is unaware of this fresh danger, consumed only by his blighted past and his current action of treason. Soon, the paths of these men must converge, and the moment of reckoning will be upon them all.
