William and the Clyeophos

At 14 years old, William has had enough of life in general. He lives with his grandparents after his parents and sisters were killed in a car crash quite recently. His favourite sport, football, hasn't been going well for him either, he plays in goal for his local team, but he seems unable to even catch a cold these days!
During one dismal game, William is handed a note by one of the few spectators.
When a woman called Esmerelda enters his life - things change after she tells him she is a being of magic and space travel. William also has two thugs chasing him: Scrag and Scar-face, bullies from his school, who are working for the weird old man called Dionysus, who wants what William has dug up.
Before William knows what is happening, he finds himself on a spaceship as the capsule he dug up has now entered his body.
The crew of the spaceship are escaping from Dionysus, who is from a race called the Sandriones. He somehow finds William, Esmerelda and his new friends. How will he escape and can he rid himself of the capsule? Why has Esmerelda been keeping an eye on him and why can't he be left alone?
