North

A decade has passed and the halfkind revolution has taken form. This underground species has built the foundations of their revolution and they grow stronger with each day. The rest of the world has no idea what's in store for them.

Leading them is one of the most powerful beings the world has ever seen. She is merciless, she is fearless, she is their mother.

However, the United Species Alliance is also evolving. Through political dealings, shady contacts, and the remnants of Project Alpha, General Rox has commanded a new wave of weapons designed to keep the world in order. His technological advances have brought fear into the heart of his enemies, but their blueprints are also in the cross-hairs of his greatest enemy, The Collector.

What separates the Halfkinds series from the rest isn't only its unique premise, but also its structure. Chapters shift between the first person POV's of key characters and are presented in a non-linear fashion in order to create a mounting suspense that will keep the reader
riveted until the end. Various plot twists occur within the story, and the different character viewpoints help alter the tone as you go along to give an unbiased presentation of their motives and actions. The setting allows a diverse cast of characters, some human, many not, to send a message that intelligence is a power that we take for granted, and when given to other species, the world becomes a dangerous place.
