what was the best book you ever read?

i don't care when or where it came from, what was just the most mind blowing work of literature ever in your opinion?

i have not read much books in my life but one book i thoroughly enjoyed reading was, "what dreams may come".

it's about a loving family, but tragedy strikes and the father dies in a car accident, but fortunately goes to heaven. the widow however, is left to raise two kids by her self and she hates this world, thinks of suicide, and she does, then she goes straight to hell.

the husband hears of this news in heaven and decides to ditch heaven and go to hell with her.

it was one of the more moving stories i ever encountered.
