In the spring of 1917, all of Britain's attention is on the WWI war front and the thousands of young men serving their country on the front lines. Jack Benningham, dashing heir to the Earl of Stonebrooke, is young and able-bodied but refuses to enlist despite the contempt of his peers.
A wealthy young suffragette, Grace Mabry will do anything to assist her country's cause. Men like Jack infuriate her when she thinks of her own brother fighting in the trenches of France, so she has no reservations about handing him a white feather of cowardice at a posh masquerade ball.
But Grace could not anticipate the danger and betrayal set into motion by her actions, and soon she and Jack are forced to learn the true meaning of courage when the war raging overseas suddenly strikes much closer to home and their fervent beliefs become a matter of life and death.
