I'll be honest.
There's another book with a similar cover that also has 'light' in the title. I was roaming the cramped shelves of a converted bus at a flea market. It was hot and through the window I spotted a lull at the ice cream kiosk -- so when I glimpsed this novel, I snapped it up. Later, a few pages in, I was curious to see how the author was going to segue us to World War II Europe ... and then I read the back cover.
Good things come to those who eat ice cream.
This is the one about Lucas Goodgame, who, in the aftermath of a horrific, present day event, writes letters to his Jungian analyst, Karl, pleading for his help. They come to reveal what tragedy unfolded and how the people of the quiet Pennsylvania suburb are trying to move forward in its aftermath. We follow along on Lucas's journey of grief, delusion and ultimatey healing. It is one heck of a ride. I enjoyed every minute of it. Even though it wasn't about World War II Europe.
