First Machu Picchu Considered one of the Seven Wonders of the World, the ancient, awe-inspiring ruins sit high in the Andes Mountains. It’s no wonder Sam and company want to visit.

Now, the vampire detective must deactivate the badness before all hell breaks loose. How to deactivate it, she hasn’t a clue. But one thing is her family vacation is about to get really, really weird.

Next Xibalba—the Mayan Underworld Fresh from a harrowing trip into a very different underworld, Sam is about to discover Xibalba is just as harrowing—only this time, she has Allison, Tammy, and Paxton with her to worry about. It all begins when Sam and the gang arrive on a sightseeing tour in Guatemala. Immediately, Sam senses something is off. In particular, that someone needs help. Sure enough, a young mother runs up to Sam, desperate for help. The vampire investigator soon learns why. Her boy is missing; worse, he might have been abducted by his father and taken to a nearby cave entrance. And not just any cave the gateway into Xibalba, the legendary Mayan Underworld. Except this is no legend. It’s the real deal, and it’s the stuff of nightmares. True, Sam has had enough of underworlds, but there’s no way in hell she isn’t going to try and find the missing boy. And so, the hunt is on. Bad guys and demigods, beware. Sam is on the case.

Next El Dorado—The Lost City of Gold It all begins shortly after Sam and company arrive in Colombia, when a disembodied head awakens them in the middle of the night. Turns out, the head belongs to the famous explorer, Sir Walter Raleigh, who lost it to an executioner’s ax 400 years earlier. The very essence of determination, the intrepid explorer isn’t about to let a little thing like death stop his search for the legendary City of Gold. And so, when Sam’s tour group gets transported to another place and time, the vampire detective suspects the ghostly explorer had something to do with it. Unfortunately, the city of gold is brimming with danger, and when Sam comes across a child about to be sacrificed high atop a golden temple, she springs into action. Now, the race is on to save a child, escape the bad guys, and find a way home. All in day’s work for Samantha Moon, vampire private eye!

Next Peru and the Nazca Lines The massive hieroglyphs carved into the soil of the Nazca desert in Peru have perplexed archaeologists for decades; after all, the glyphs can only be truly appreciated from high above. When Sam and her magical crew arrive in the desert for a sightseeing trip, they have every intention of exploring the famous animal figures etched into the sand. But when a little bit of magic is used by Tammy, the spell sets off a powerful explosion that lands Sam and company in a world very similar to ours. A world where the drawing carved in the sand depicts real demigods—and one such god has taken exception to Sam’s presence. Now, with a legion of blood-thirsty followers chasing them, Sam turns to an unlikely ally. Something deep beneath the desert sand, something massive... Something that’s been waiting for them for a very long time.

Next Easter Island On a beach in Chile, the unimaginable happens. Magical cultists kidnap Tammy and Paxton in a blink of an eye—literally.

Turns out, the cultists were dead set on sacrificing Tammy and Paxton to a local god. That was their first mistake. And as all hell breaks out on the isle, including something ancient and massive crawling out of the earth, Sam and the gang are in for the fight of their lives.

Final The Amazon On a helicopter ride over the Amazon River, Samantha Moon thinks she sees a demon outside the window. A small demon, granted, but a demon nonetheless. And when the rotor blades stop working, and the chopper full of tourists starts to fall into the dense vegetation below, she’s pretty sure the demon had something to do with it. As the helicopter plummets, it takes all her supernatural skills to keep everyone alive. Somehow, she manages to... except there’s one they’re now stranded deep in the Amazon. Sure, Sam could teleport everyone out, but she would be forced to wipe away hours of memories—a challenging task that might not even stick. Instead, she leads the group of tourists through the thick forest and towards safety. Safety being the operative word here; after all, there’s something else hunting them in the forest. Something much, much bigger than pesky little demons.
