The Medici Manuscript by C.J. Archer

Sylvia is still working in Glass Library with Professor Nash and they've discovered an interesting manuscript. There are markings that seem like the book may have come from the well-known Medici family. But there are other markings as well. Some that seem like they might point to some potent magic. 

The whole gang is there again, Sylvia's friend, Gabe, Gabe's aunt, and his friend. And they're all trying  to figure out what they mean. But then the book disappears. Plus, there's the whole "people trying to kidnap Gabe" issue and him discovering more about his own magic.

An interesting addition to the series and at least one impediment to the path for Sylvia and Gabe gets removed. But that plot point could come back later.
