I really enjoyed this book. In a world of unlimited urban fantasy about werewolves, vampires, zombies, etc, the original idea of having immortal humans with (limited) special powers was a breath of fresh air. Not only were the plot and characters unique, but Kimberly Chapman managed to cover an entire gamut of themes as well! And while this book technically is a romance novel, it is actually a very intelligent and romantic story about the journey of two people, and doesn't really comply to the smutty, guilty-pleasure stereotype of the romance genre.
The story follows a man called Jason Pruitt, the head of Gaia Global, a large environmental agency. But he's not any ordinary man, and there's only one other person in the world that he knows of that is like him. Gradually the reader discovers that Jason and Anna, originally referred to as 'Gaia', are immortal humans, and each of them has their own special power. A variety of themes are brought up naturally throughout the plot and character development in the novel, including the role of environmentalists, animal testing, proper female behavior, male dominance, sexual assault, ignorance, gay marriage, sexuality, science, loss, loneliness, and love. In addition to all of these themes, Kimberly also managed to have an incredibly interesting plot full of all sorts of tension and twists and turns, as well as amazing character development. All of it put together made this an incredibly exciting book that I had trouble putting down!
