I am so sad about Michael's passing. I know we all have to go sooner or later, but when an author dies, I not only think about all the stories they left behind, but the stories they took with them.
So sad. I've read a few of his books and met his son, also an author, at Bouchercon last year. He spoke so highly of his father.
It's funny how you feel loss when it's an author that you read - even if you've never met that author. I felt the same with Vince Flynn's passing.
