Questionlesse he will be dead

Razi is a fourteen-year old who is left on his own for three days after his older sister goes off on a 'shopping trip'. Razi finds a book of potions published in 1614, and sets about finding the ingredients for a very special potion. As he comes to terms with new magical powers, he has to deal with a nasty accident, a gang of violent racists, and an angry Rottweiler that wants to track him down and kill him. But the greatest danger of all comes from the woman whom Razi unwisely summons from the green fire, and whose only mission is death.
