1) The Diary of a Young Girl - Ann Frank - This book was recommended to me by a friend. Though I dont read non-fiction much I finished this book in one sitting. It is very emotional and though-provoking.
2)The Prodigal Daughter - Jeffrey Archer(My first JA and totally loved it, inspires me that if you really want to you can achieve anything)
3)The Inscrutable Americans -Anurag Mathur (Really humorous and I read it after my 1st visit to US, so could totally relate)
