Shadowland (Book 3 of the Immortals Series) by Alyson Noel

Damen and Ever are back again in the aftermath of Roman's wake. But unfortunately Roman is not done. Damen is cursed and if he comes into physical contact with Ever, be it brush of the hand or lips, he would plunge into the Shadowland, a place where all immortals go when their souls have nowhere else to go. In their desperate search to find a cure, Roman starts playing games again. But the entrance of Jude into Ever's life sends everything spiraling out of control. She's drawn to Jude like she's never been drawn to anyone but Damen. Before long she's going to be forced to make the most painful decision of her life.

I really like this series. At times Ever can definitely seem a bit naiive and she tends to act a bit rashly. She knows Roman is bad, yet she is so desperate that she's willing to trust him. But nonetheless, I still like it and I highly suggest it to everyone out there looking for a bit of a change from the usual vampire lore.
