Wow! 
 Happily ever after doesn't mean a lifetime of perfection. I don't think anyone believes that happily ever after means there are no unhappy days, even unhappy years. It means loving forever, despite all the many reasons it's easier not to. 
 There is this movie with Robin Williams, "What dreams may come". You most likely remember it. Chris loses his children, his life and suddenly he is in heaven and he is not happy because his wife is somehow in hell, lost in her crazy mind. And he tries to find her, he keeps looking for her because heaven without his only love equals personal hell. He knows that she exists, he knows that she is real and she needs his help because he simply believes this fact: 
 What's true in our minds is true, whether some people know it or not. 
 And he finds her. 
 You may ask, 'why is this relevant to this book?' 
 Well, this book is not what you think it is. This book is basically a journey to the human mind. 
 Yes, it is romance. 
 Yes, it talks about pure love and commitment. 
 Yes, it is about two people who have fallen in love. 
 Yes, there is happily ever after. 
 But nothing is what is seems. 
 But nobody is who you think he/she is. 
 But there are twists and turns that they may make you gasp "WTF" many times. 
 When the main male character from the book says to Lily: 
 If you go away, then I'll come and find you, even if it means I have to get lost for a while, too 
 , 
 I think I was crying harder than the first time I watched the Robin Williams' movie and there was this scene when he finds his broken wife and tells her: Annie, I'm here babe, I still exist. 
 Please, be open-minded when you start this book!
