Portal to Xibalbá

After years of hard work, Tyler built his IT Security company into a massive success. He trusted his people and now it was time to enjoy the fruits of that labor. Everything was perfect until an unexpected discovery. Should they go through the Maya portal? Adriana's small diving instruction shop is popular enough with the tourists for her to scrape out a living, but it's not the life she expected. When she got the call, it seemed impossible. Wasn't Xibalbá a myth? In a fantastic world of danger and possibility, two people want to discover the truth, but for entirely different reasons.

Months after the expedition through the portal, Tyler Drake is still struggling with the gruesome consequences. So the call for help from Mexico comes just in time: Adriana's brother is missing—and seems to have made the journey alone to the world beyond the cave. Another race against time begins—and this time, the team has to contend with not only the dangers of an exotic world but also with terrestrial adversaries and an extraterrestrial threat, the existence of which they never even suspected. Will they succeed in saving not just one boy but an entire world?

An alien being has escaped to Earth. The portal is occupied by American troops, and the only humans who have ever set foot on the alien planet are in CIA custody. To make matters worse, a hostile force is now threatening both Xibalbá and Earth. Can Tyler and Adriana save their new friends on the other side of the portal—and save their home planet from invasion at the same time?
