They may be for later. They're for my kids for later, but they're for me for now. I read the wizard of quarks so far and half of once upon a universe. They are nice to read. I randomly remember stuff I read from them, so , that's cool. They're quite worth the valuable bookshelf space. So is The Disappearing Spoon, which is a trivia book about the periodic table of elements and transmutation. It's another well written book that's enjoyable and you walk away feeling like you learned something and enjoyed reading it so much you look forward to reading it again in a couple of years and learning something else. That's my criteria for staying in my bookshelf.
