The Hybrid Chronicles: The Complete Series

The hybrids are a family of soldiers who gave the ultimate sacrifice - and found themselves healed with a mix of animal and human stem cells.
Treated as less than human, they continue to serve - until a mission goes completely against their morals and ethics.
Life, when you are different, isn't easy. Bitter moments and sweet. Then they tell you to 'be the change you want to see'.
When you're trained to serve and fight, sometimes you take the battle to the streets to incite that change.
