The Sorceress (The Secrets of the Immortal Nicholas Flamel) The Sorceress is book three in The Alchemyst Series. Read the whole series! You won’t regret it.
The Magician (The Secrets of the Immortal Nicholas Flamel)Even though this is marketed to “young readers” I found it on par with the Harry Potter series. Maybe not as deep or as macabre but the mythological tone worked for me and the action and magic was great fun! This is the second book in the Alchemyst series.
The great book of Amber: the complete Amber chronicles, 1-10If you are sci-fi and/or fantasy fan and you haven’t read Zelazny’s Amber Series you’re in for a treat! Full of believable fantasy with depth on par with Tolkein. The first 5 books are better than the second 5 so if nothing else do those! 🙂
