The Alchemyst by Michael Scott

Nicholas Flamel appeared in J.K. Rowling's Harry Potter-but did you know he really lived? And his secrets aren't safe! Discover the truth in book one of the New York Times bestselling series the Secrets of the Immortal Nicholas Flamel.

The truth: Nicholas Flamel's tomb is empty.

The legend: Nicholas Flamel lives.
Nicholas Flamel is the greatest Alchemyst to ever live. The records show that he died in 1418, but what if he's actually been making the elixir of life for centuries?
The secrets to eternal life are hidden within the book he protects-the Book of Abraham the Mage. It's the most powerful book that has ever existed, and in the wrong hands, it will destroy the world. And that's exactly what Dr. John Dee plans to do when he steals it.
There is one hope. If the prophecy is true, Sophie and Josh Newman have the power to save everyone. Now they just have to learn to use it.
