Tide Vs The Island Wizard

A tale told many times in many waysa boy and his dog on an adventure. The slight variation in this story being the dog is dead the boy has no memories and they just happen to be on an abandoned island with a psychotic wizard. Really it's like any one of the classics. The main characters Tide (the guy) and Bo (the spirit Dog) may not know what is going on but they are going to need to stay alive as more and more foes appear and are only out for blood. Lucky for them they hold very special abilities between them that will aid them to hopefully have a chance at survival.(The book is read in the Traditional manga format however it is entirely in English.)
