The Alchemyst: The Secrets of the Immortal Nicholas Flamel by Michael Scott
I listened to this book on CD and thought it was really good. It is an action packed story that takes place in modern day California. Twins Josh and Sophie get caught up helping Josh's bookstore boss, Nick Fleming who turns out to be the immortal Nicholas Flamel. Flamel has been protecting the book of Abraham the Mage, also called the Codex, which has the recipe for keeping him immortal, along with lots of other prophecies and information. It is stolen (except for 2 pages that Josh has torn out) by another immortal, John Dee. One of the prophecies involves twins, so Josh and Sophie are pulled along for a wild ride as Flamel tries to retrieve the Codex. They meet all manner of creature, god and goddess from legend and myth. It doesn't really end...there will definitely be sequels. I'll give it a YAY because it's exciting, makes you want to know more about the mythical creatures, and is great good vs. evil plot.
