Emelia must choose. Her sister or her soulmate. In a world not dissimilar to our own, the Administration have ensured that the human race should not have to live with any regrets. Like millions before her, Emelia now has the chance to go back and make the 'correct' decisions. The little envelope that contains her amendment will change not just her life, but that of the people she loves the most. Her sister Finola, whose reckless and self-destructive nature have lead her dangerously close to the sinister Marchers movement; and Gabe, the rock that has been holding the remnants of her family together for as long as she can remember. Caught between saving Finola or happiness with Gabe, she must struggle to predict how the ripples of her amendments will spread. Two envelopes, two choices, one life. What would you amend?
