Archie Takes Flight is the first in the Space Taxi series by Wendy Maas and Michael Brawer.
The book opens with Archie expecting to ride with his dad for "take your child to work day" but, as the title suggests, this is no ordinary taxi. Eight year old Archie has just found out that his dad drives all over the universe. They pick up some interesting characters as they travel through space. They even help solve inter-galactic crime and still make it home for breakfast. I was really surprised by the ending but it made me want to read the next book in the series.
This book is not available in the Classroom Library, so check it out from the Pollard Memorial Library and read it over summer break.
