Darkness Falls by Cate Tiernan (second in the trilogy)

Darkness Falls by Cate Tiernan starts off two months into Nastasya's stay at Rivers Edge, a sort of rehabilitation home for wayward immortals.  Nas has overcome some major obstacles and she is starting to allow herself to get close to all of those around her when things start to go horribly wrong.

The more Nas discovers about herself at Rivers Edge, the more she starts fearing that she is a child of dark magick and that she is the cause of everything that is going wrong.  Nas starts pulling away from everyone and after one horrific evening she ultimately runs away from Rivers Edge. 

While in the middle of the woods surrounding the farm, who should come upon Nas but her old friend Incy, the immortal she came to Rivers Edge to get away from in the first place.  Not only that, she has been having recurring nightmares about him recently, but Incy is being so sweet and kind, she begins to second guess her reasoning for running away from him in the first place and leaves with him.

Nastasya is happy to be living a luxurious life full of fun, fabulous clothes and gourmet food with Incy, especially after spending months at the farm doing menial tasks and only eating what they harvested.  Underlying all of this though is her nagging suspicion that maybe she should have stayed at Rivers Edge.  Her thoughts keep going back to River and Reyn, but she brushes it all aside talking herself into believing in Incy.

Big mistake!  I couldn't put this book down - I kept thinking Run Girl!!  I am telling you - read Immortal Beloved and pre-order Darkness Falls, which I give a rating of five out of five!
