Magic School Bus meets The Magic Tree House in this third installment of a school-based chapter book series by bestselling author Nancy Krulik. When their teacher takes them to Romania, will this class be able to tangle with vampires?

Ms. Frogbottom’s class is on a field trip to Romania where a visit to Dracula’s castle brings them face to fang with vampires, garlic, bats, and—yikes!—could it be the legendary count himself?

Bestselling and beloved author Nancy Krulik ingeniously approaches geography in a new way, as the kids learn about the places they visit while fighting, fleeing, or in some cases rescuing monsters.
