Things had changed a lot in Alastair's life since he found the little blue dragon he named Spike. Now it was time to start back to school and Alastair was faced with entering the fourth grade with the dreaded Ms. Cassowary as his teacher. All his lucky clothes on the first day didn't help and things got worse as the weeks went on.

On top of his school troubles, his pet dragon was depressed because Alastair was gone all day. Then there was the mysterious face peering in the window. And why was Alastair being followed when he took Spike for a walk?

He seeks help from his best friend, Josh, and his Uncle George, a research scientist. Together they struggle to keep the dragonnappers away.
