I was always a fun of stories about extremes, about very different people who are attracted and finally fall in love: the lady and the tramp, the princess and the poor soldier, the sophisticated woman and the plain farmboy, the defendant and the ring fighter, Grier and Isaac. 
 I loved their story. 
 The book also included people full of regrets, many prayers, fallen angels, a sad ghost, a scared father, an addictive videogame, a persistent demon, many lies, hidden truths that finally see the light and a war between heaven and hell in full force. The perfect recipe .
