Dark Duality

Cate is tired of watching from the shadows, helping innocents at the last possible moment when she could be doing something beforehand. She knows that a great evil is at work and it won't be long until the supernatural and human world are at stake. She needs to be a guide for those she wants to protect, and it all starts with Grayson Cross.
...
Grayson isn't sure what to think of the random female who turned up on his doorstep. She isn't human, but she also isn't anything he has come across before. She says there is a war coming and they need to prepare. She seems to know information other people don't. Despite her flirty actions and not so amusing antics, she's distant. And Grayson needs to find out what's she is hiding before it's too late.
