Time is running out; who will get there first?

In a pre-industrial society, combined with a small use of high technology, four adolescents get to travel, explore, and discover new ways of training their essences with masters in different locations. While resting in a quiet and charming town, Ion, Cedrus, Cleomé, and Adeline learn about an ancient source of power called "Immortal Essence". The four teenagers are recruited into a risky mission of locating and retrieving this legendary entity, but they must also secretly race against the dangerous ruler of Karoush, High Master Zadur, in finding it.

Ion is a recently-turned-15-year-old boy who prefers to sleep on the ground instead of mattresses, he sometimes still acts like a 10-year-old, and he sees the world with an optimistic point of view. Then there is a sweet and loving 15-year-old girl named Cleomé who is bubblier than champagne and the most motivational person anyone could meet. She has the gift of being able to make almost everyone open up to her, no matter how introverted they may be. She is even able to reach the heavily guarded 16-year-old Adeline. Adeline is a hunter, a loner, and a very cunning girl. She has trouble connecting with people, and making friends does not come easy to her, but she finds a friend in Cleomé and the boys. Cedrus is a responsible but sometimes playful 16-year-old boy who looks like he could bring down a building. He loves combat arts and is very good at setting goals and following through with great discipline. He also happens to be Ion's best friend.

Immortal Essence is the first book of a series of young-adult fantasy novels.
