Lilith Evolved Tesla's Mana

Tesla's Mana.

Lilith Ulrich, a genius and energy enthusiast discovers energy in its purest form; Mana, a form of natural power produced from billions of sparks of life, and the birth of all matter on Gaea. Together with her friends, she will manipulate the energy source with hopes of creating a never-ending source of power. Until their work with Mana gets on the radar of powerful companies in Gaea and an otherworldly council bent on keeping their control over humanity.

In a dimension, a jump through a portal away from Gaea, a civilization exists on a plane separated from the human world by world lines. The dark council presides over this old world full of brilliant lights and strange entities and they—until Lilith's discovery— have the monopoly on Tesla's Mana. 

Tesla's Mana is the first book in the Lilith Evolved series.
