I adored the premise of this tale--a Game between Love and Death, each selecting his or her character to see which will ultimately rein. This is a love story, of sorts. It's the tale of two people destined to be together, but there is a time limit to the game. And if Love's criteria is not fulfilled by a certain day, then Death wins. 
 Love and Death themselves are what makes this tale. Their chosen pawns... are lacking. We're to believe that Henry and Flora are fated to be together, because their players have hand-selected them for this edition of the Game. Naturally, they are to fall in love. But there's no basis to that love. It's an instantaneous bond, one that we're to believe bloomed in childhood, as if one minor occurrence when they're children means anything in regards to fate. 
 Quite honestly, not a lot happens in the story. It's a lot of telling: Henry loves Flora. Flora feels depressed. One of my biggest pet peeves in writing is too many unnecessary details, i.e. "he made a sandwich and then ate the sandwich and chewed it." If the sandwich isn't important, for goodness sake don't tell me about the sandwich. 
 The end redeems this a little, because Love and Death themselves become part of the story, too. Death is a wonderful character--her own fate is awful, and she knows it, and it makes her cunning and manipulative. Love, too, has his tricks, and just because he's Love itself doesn't mean he's not a cheater. 
 This is a Game between Love and Death. Their chosen players contribute little to the actual story, which is unfortunate seeing how much of this story focuses around them. I would 100% read a tale just on Love and Death and their antics.
