The Cronos Trilogy

Humanity is on the edge of extinction. An alpha predator, known as Chimeras, has made its claim to the lands as the top of the food chain devouring all those unlucky enough to cross its path. However humanity is also divided, not only in politics and by distance, but also technologically. Zenith claims its spot as the foremost advanced on the planet with Atrium as its competitor, while Carshire is far behind either but has delved into the unknown and have come out as masters of the elements. Devon Thorne was born outside of the Capital of Atrium in the far away town of Serenity. In the chaos and confusion of a Chimera attack, he and his sister, Rose, are taken and drafted into a program started by the world renowned scientist, Doctor Johnathan Seraph, to create the next generation of warriors. Like all things, they are not as they seem and Devon must find his way out of a possible civil war, with him and his sister at the center of it.
