Looking for something "life changing" to read.

[Crunchymum]

Nothing to complicated or niche.

I have just stated reading again after many years of not having the time / inclination.

Last book I read was "A State of Fear" which was hard going, but thought provoking (if not life changing)

My all time favourite book is "Nineteen Eighty-Four"

I'm open to all suggestions. Thanks

Roots, and yes I know all the criticism.
The life of pi
Birdsong
The story of a slave girl written by herself (fascinating insight into the last period of chattel slavery in the US)
The Isles, a History.
