Shadowland by Alyson Noel
Ever and Damen have travelled through countless past lives - and fought off the world's darkest enemies - in search of each other. But just when their destiny seems finally within reach, a powerful curse falls upon them. A single touch of their hands, a soft brush of their lips will mean death for Damen - cast into the darkness of the Shadowland. But as she seeks to break the curse, Ever meets Jude - a green-eyed, golden surfer boy who understands magick, and understands Ever better than she realises. And she begins to ask a terrifying question: even if you're immortal, can true love really last forever?
