Query: lost and gain

I lost a brother, he drove too fast, he had good times, but they didn't last.he made my whole family, weep buckets of tears, he made my world, seem so unclear.I bought this book, it touched my heart, it talked to my soul, every single part.I was back up on my feet again, ready to face the pain, Clarity was what i expected, and i recieved it...the world was perfect.
