We couldn't improve on Colleen Cahill's review from Feb. 2006.

Cartomancy is defined as fortune-telling with cards, but in the case of this second work in Michael A. Stackpole's The Age of Discovery, this term deals more with cartographers than cards. The fast pace continues in this exciting adventure, which has plenty of intrigue, mystery and passion. The actions of one family will affect the fate of an entire world, perhaps bringing a past tyrant back in to power.
