Two lives in danger - her lover's and her sister's. But she must choose only one.In 1913, young Irish emigrant Eva Downey is trapped in London with a remote father and hostile stepmother. When she is awarded a legacy from an old suffragette to attend a finishing school in Kent, she jumps at the chance. At the school, she finds kinship and later falls in love with her teacher Christopher Shandlin, her intellectual equal. But when war breaks out and the man she loves refuses to fight, Eva's fanatical stepsister Grace pushes her to make a choice. She must present him with a white feather of cowardice, or no money will be given for her sister Imelda's life-saving treatment in Switzerland. Caught in a dilemma, Eva must choose - and her decision will have irrevocable consequences for her and Christopher and haunt her for the rest of her life.
