An excellent book grabs you from the opening line (though if not done well, 'openers' can seem to strain towards suspense rather than grab one's attention). I just finished, for the second time, "The Glass Castle," a memoir by Jeannette Walls, and it begins like this:
I was sitting in a taxi, wondering if I had overdressed for the evening, when I looked out the window and saw Mom rooting through a Dumpster.
Doesn't that sound interesting?? The book is fascinating! A memoir full of deep poverty and suffering, yet devoid of any self pity. I highly recommend it.
