Your regular beloved sixth grade teacher doesn't show up after spring break. Instead, a handsome, strict and by the book substitute teacher is there in her place. You soon find out he's an alien who is intending to kidnap 5 students from your class. Who is going to believe you? Will you be able to stop this alien from achieving his mission? Read what Susan Simmons does as she faces these difficult questions and dilemmas. This very appealing book sold more copies for Bruce Coville than any of his other books combined. Once you start reading this first book in the series, you will soon find out why it's so popular and race to read the remaining three in the series.
