In Raven’s Gate, the first book in this series, 14-year-old orphan Matthew Freeman is at the mercy of his foster mother and her neighbors — all modern-day witches — who plan to sacrifice him to free evil creatures called the Old Ones from another dimension. Matt is one of five children prophesied to save the world from destruction.
In Evil Star, Matt lives with reporter Richard Cole, who helped him escape the witches. The Nexus, a secret group sworn to protect earth from the Old Ones, provides for them. When an attempt is made on Matt’s life, the Nexus tells Matt of a diary containing prophesies about the Old Ones and the five children. The diary has fallen into the hands of a corrupt Peruvian businessman named Diego Salamanda, and the Nexus is convinced that he plans to help the Old Ones escape from a portal in South America. Matt and Richard fly to Peru to meet with Nexus member Fabian. When Richard is kidnapped, Matt flees and meets a street child named Pedro, another of the five children mentioned in the prophesy.
Pedro and Matt go to Salamanda’s home to search for Richard. Discovered by Salamanda, the boys are rescued by a driver who tells them to find his brother, Atoc.
The boys travel to Cuzco to find Atoc and call Fabian for help. When the city is flooded with Salamanda’s men, Atoc rescues the boys and takes them to a secret Incan village and to Richard. Richard was never kidnapped but taken for his own safety. The Incan sorcerer called an amauta predicts elements of what the boys will experience in the days ahead.
The Incas send Richard, Atoc and the boys to meet Professor Chambers. She studies and writes about a strange set of animal pictures drawn in the sand, which are so large that they can only be seen from the air. She believes these symbols may be a warning about the end of the world.
Salamanda puts a satellite into orbit so he can align the stars and allow the Old Ones to escape near the sand symbols. With the help of a small army of Incas, Matt and the group raid Salamanda’s satellite station, where they find Fabian and learn he is a traitor. Matt uses his power to blow up the station, killing Fabian and others, while saving his friends. When Matt attempts to disable the satellite, Salamandra tries to kill him. Matt deflects the bullets with his powers, which kills Salamanda with his own ammunition.
The Old Ones escape, erupting from the ground in the form of massive creatures before shape-shifting into swarms of flies, an army of men, freakish, unrecognizable shapes and then skeletons. The terrifying King of the Old Ones emerges, and it takes all of Matt’s and Pedro’s supernatural powers to fend off the army. Though they’re able to drive the Old Ones from sight, Matt feels with his precognitive powers that they will be back. Matt and Pedro realize they must find the other three children in the prophecy so they can protect the earth together.
