The Magician: The Immortal Secrets of Nicholas Flamel by Michael Scott
If you haven't read the first book, The Alchemyst, this is a *spoiler alert* for that title.
After going through the ley gate, Nicholas, Sophie and Josh find themselves in Paris. Sophie is Awakened; Josh is not. This puts them somewhat in conflict with each other, even as they find out more about their powers and find themselves up against Machiavelli (yep, he's immortal too).
Well-paced and a fun read. Small things bugged me in this one, like the first, but I'll keep reading because I want to know what happens. 4 stars.
