I'm reading "A Grief Observed" by C. S. Lewis.
It's a short book, only 76 pages in total and that with generous spacing on each page.
Because I haven't got much time for reading lately, I chose this book, so I can get through it without too much delay.
I'll probably give a longer review on the book sometime later, but all I can say, or need to say about the book at the moment is that in this book, C. S. Lewis is brutally honest. He articulates his wandering thoughts and grieving love for his wife in very much detail, that I am discovering a Lewis that I never knew before.
You can get this book from Amazon.
