Spirituality is my favourite genre. I am currently reading 'Power of now' by Eckhart Tolle, 'Synchrodestiny' by Deepak Chopra and 'Decision Points' by George W Bush. I follow just my heart when it comes to deciding a book to read and at one given point, I read 3-4 books.
Depending on what I feel like reading, I just pick that particular book and read. I don't take any extra special care of my books but make sure I keep them in good condition. I love book marks too.
