The young adult adventure The Truth About Magic, narrated in jolly Scottish refrain by Stanley McGeagh, concerns Mr. Tipkins, a "gift giver" (i.e. elf wizard), who had to deliver a "gift" to a new baby, Alan.
Unfortunately, Tipkins was in the middle of one really bad day. It was a long and uncomfortable journey to find the baby (Tipkins flying carpet was out of commission - he instead having to fly on a cheap cushion) and when he finally did arrive, a final minor slight led Timpkins to lose his temper. And wizards with tempers should be avoided at all costs.
As a result, Timpkins gave baby Adam a much more powerful gift than intended. Oops.
The Truth About Magic is a story of mistakes and of deception, of wizards (good and bad), and of what happens when perfectly ordinary wishes go wrong.
