Mel Beeby's eighth adventure takes her to medieval Japan, searching for a lost soul. Mel and Reuben have been studying Soul Retrieval, running through all manner of challenging scenarios in virtual reality, in order to learn the specialised skills necessary to rescue human souls. The two angels are sent to Japan, to try and reunite a young girl's soul with her body. In their quest for the soul, Mel and Reuben have to enter a realm that's magical and exquisite, like an idealised Japanese fairytale dream, but like all dreams it has its dark side, and the Japanese after life has some extremely scary aspects. Mel and Reuben must stick together . . . and at the end, there is even a little hint of romance for our two angel buddies!
