An Ancient Arrival - John & Andy - Book 1 - John & Andy, #1

Nobody expects to wake up to find an alien sharing their brain, but that is exactly what happened to John. Andy is an AI who can access the memories of long-dead hosts spanning hundreds of thousands of years. With Andy as his guide, John, a geeky 10-year-old, morphs into Mr Popularity. Andy is sure his/her/its brain-mate needs to grow up fast and tough in order to confound the evildoers who have entangled his father in their horrific web.
But Andy has no moral compass, no soul and scant regard for the law. Will the loss of his blissful innocence be a price worth paying for John to protect his family? An Ancient Arrival is Book 1 of the John & Andy series, beginning in October 2010 near Reading, England. A sometimes amusing, sometimes dark fantasy saga featuring light-touch story-telling reminiscent of Three Men in a Boat but without the men, the boat, or the dog.
It does include boys, girls, parents, teachers, and fascinating insights into food.
