What an amazing story! This is book 5 of "The Secrets of the Immortal Nicholas Flamel." This is the book where all secrets are finally revealed! I couldn't put this book down. I had guessed that the twin's parents had to be someone important as they weren't around. In this book, you learn who they are. I don't want to give away any spoilers, but this series is definitely worth reading. I've decided I'm going to buy the saga for my personal collection! If you love Magic & Fantasy... this saga is it! Great job author Michael Scott! Can't wait to read book 6, the last and final book of the series!
