I am not sure this is a book one may read in order to be 'persuaded' (not that you implied directly that, of course).
My humble opinion is that spirituality and awareness are things one feels strongly inside him/her and thus decides to explore them further.
I personally started in my late teens by reading Paramhansa Yogananda's book "The Autobiography of a Yogi" and other works such as those written by Peter Uspensky. In the beginning Uspensky and Krishnamurti were hard to comprehend.
In the early '00s I started reading (selectively) works from Swami Vivekananda and that was when my G.P. (who practices Ayurveda) introduced me to the teachings of Sri Ramana Maharsi and Nisargadatta Maharaj. I consider the talks and teachings of both Maharsi and Nisargadatta the epitomy of spiritual reading. Now that I go back to explore Krishnamurti more (as a side/complementary teaching material) I can comprehend way better what he's talking about.
There is an invaluable
recorded satsang showing Nisargadatta himself. It's true fire, absolute dynamite with regards to the way he talks and passes messages along. Truth is though that it takes steady practice and determination in one improving thyself so as to advance their awareness and spiritual level. I strongly believe that anything one needs to know is contained in the short teachings and talks of both of these two great gurus, who were actually very different from each other in the way they expressed their thoughts (Maharsi was speaking through silence and Maharaj was dynamic, confronting, challenging).
