Harry's enhanced his musical and artistic talents, and Hugo, at age 10, had the appearance and strength of a body builder. All resented having to take the pills and were suspicious of their parents' motives. Tandy's investigation also turns up some disturbing surprises about her parents' lives.
Tandy proves to be a pretty good detective, and may be back in future mysteries. She is too pushy, mouthy and headstrong to be a real likable child. But, then, she's not your grandma's Nancy Drew.
