I finished Antiphon, the third book in the Psalms of Isaak series. I have the 4th book, but I'm holding off because the 5th and final book doesn't come out until December. So I started What If by Randall Munroe, the talented cartoonist behind the XKCD web comic. I didn't realize that Munroe was an NASA scientist before quitting to go full time as a cartoonist. This book presents science questions that have been asked by his readers and he answers them with his unique blend of science, sarcasm and humor. The first question was "What would happen if the world stopped spinning?" and I almost couldn't sleep when I finished reading his answer! Let's hope that never happens, but if it does, the moon will be our best friends. I think I'm really going to enjoy this book!
