This is quite an interesting book, that will keep you hooked from the beginning. The author uses an idea that one's conscience can leave the physical body and travel to other realms. Based on this idea, his story develops when Mark, our hero, and his two best friends (Carla and Jonas) decided to test if the so called astral projection works and they decided to try it and do an experience to prove this theory. But what Mark really wants is to meet his dead mother once more. But during this trial, his best friend Jonas is captured by the Guardian of the Threshold, an evil entity that try to prevent non dead persons to enter into his realm. Now their only option is to go ahead trying to rescue him. And they happen to count with an unexpected help from someone in the Threshold. The story is written in a very fast path and it is guarantee that will keep you entertained for some hours. It took me around ten hour to read the whole book.
I recommend this book to the permanent library of any reader that is a fan of paranormal novels. I bought this book from amazon.com in its electronic version. Opinions expressed here are my own. ( )
