Nina and Leo are two individuals with their fate intertwined. Her father used to tell her tales of shape-shifter creatures of two kinds: Dark Dragons and ShadowCats. Leo knows of these tales too, but also knows that they are more than just myths. He knows that both species are as old as time, and between them was created a civil war; the survival tournaments. This tragic ‘game’ like event causes assassinations like no other seen in the history of torture, every 500 years. Yet how did the world manage to ‘forget’ about these creatures? Due to Nina’s bloodline she’s targeted by Stephan; a powerful Dark Dragon, the reason for her father’s death and possibly the deaths of millions of ShadowCats whom her grandfather’s agency is responsible for protecting. Her grandfather; bound by a merciless oath, strikes an alliance with an agency which has been quietly corrupted by Dark Dragons. Betrayed by his own agent, her grandfather is forced to make a decision that may cost Nina dearly, or, the entire ShadowCAT population. Whilst on holiday Nina is warned by her deceased father to be careful, but when Nina meets Leo, and both become (maybe even romantically) acquainted, their secrets spill and questions arise… But above all silent chaos, Nina realises that there’s more to Leo than meets her eye. What they don’t realise is that they’d soon need each other to stay alive.
