Sarah Yes would be my immediate answer. But if you're anything like me you won't be able to sleep not knowing. Unless you're a fan of fairy tales - don't go in with high expectations. You'll be crushed.
Nariman no dont... the third book is better than the first and second. you would learn about some of the past and the impact it has in the future. there are moments of sadness but there are moments of happiness too, even in the ending.
