Ghosts. This book basically has that element that's very different from other YA books nowadays that are mostly focused on vampires and werewolves and angels. Reading it feels so refreshing. Like something that I really have been waiting for so long in awhile. It's so good to read something new and I really enjoyed having to finally read this. Intrinsical is a very good book. One that delved me in, making it hard for me to resist. I especially admire Lani's concept of astral projecting (summoning your soul to come out of your body). Personally, I would want to read more something idea like that and I'm happy to have this book in a series. And I love the ending the most. It's kind of cliche (you know a boy and girl ended up kissing, making up those times they missed out on), but I love it. Makes me sigh in a very comforting sense. Without the ending, I might have lessened my rate into four. I recommend this to people who want something new in the bandwagon. =)
