I've read "P.S., I love you" by Ahern Cecelia. It is very wonderful book. The book's subject is grievous, but it was described very witty and funny. I would say that this book about a hope and a life.
I like this quotation "Целься в луну! Даже если промахнешься - попадешь в звезды"/"Aim at the moon! Even if you miss, you will hit into the stars."
