Sci-Fi book cover for a full length novel set in Brasilia, Brazil.
The earth was originally built by ancient alien race to house a device to balance natural cosmic energy distortions in galaxy(Balance Unit.jpg), humans developed naturally on Earth after it was built.
One species of aliens had prospered with the old imbalance and suffered under the new balance. They sent a missile into the center of the earth and damaged the balance unit (text excerpt 1). Another alien group arrived to stop them from completely destroying it.
Human development subsequently changed and we acquired a repressed ability to manipulate cosmic energy that can be used to repair the balance unit. The damage to the balance unit created a harmonic distortion that made high-speed space travel impossible so the two alien groups spent thousands of years trapped here using their available resources trying to build city-sized machines to fix/destroy the balance unit. Brasilia Brazil is the third attempt. The layout of Brasilia is in fact a large particle accelerator (Machine Plan View.jpg)
Story starts with American brother and sister (text excerpt 2), getting tricked into going to Brasilia to play a role in a battle between two alien groups. They slowly gain access to their suppressed power( Pearl becomes focused and strong, Randy has the ability to repel objects). Randy works as a crazy moto-scooter courier to earn money, Pearl teaches English. They are attacked by the "bad" aliens and discover the truth of their position, but agree to help the "good" aliens to prevent the world from being destroyed. Pearl will be the person to absorb and redirect the energy in the machine down to repair the balance unit.
Most of the action is in Brazil, but Randy gets forced to collect some objects from around the world, Lagos, Portugal; Paris, France; and Istanbul, Turkey.
Machine gets turned on in end, of course! (text excerpt 3).
