Colandra's Quest (The Cronkel Chronicles)

The first book, Colandra's Quest, is about a young man who is involved in a bus explosion. He is not killed, but an over-enthusiastic spirit in Celestina, takes his soul by mistake, and because of this, Colandra is spiralled into a sequence of events that should never have happened. By the time the mistake is realised, he has lived many lives on Earth, but now the spirits must send him back to find his body, re-unite with it, and make himself whole again. He is given the help of a human, Michelle, but they find that a demon has stolen Colandra's body and will not return it without a fight. Unbeknown to everyone, the demon has a special interest in Michelle, who is a vital cog in his evil plan. Battles rage across the universe to protect not only Michelle and Colandra, but the whole human race. The entire fabric of existence is in jeopardy and it is vital that the demon will not prevail!
