I have no idea what book to get for my dad on fathers day I was wondering if you guys had any suggestions.I think he likes mystery books but I don’t know which ones he has read so I don’t think I want to get him one.He has read all sorts of books from hunger games and harry potter to philosophy books like blink,who moved my cheese and running and being the total experience.He really likes to read and I know I could get him a gift card but I am already getting him a Whole Foods gift card and want this gift to be more personal.Any suggestions?
