Imagination Station - Revenge of the Red Knight

Since I could read and review some of the kids fiction as part of Tyndale's Summer Reading Program I did.  Personally I'll stick with adult books!  I read "Imagination Station - Revenge of the Red Knight" by Marianne Hering and Paul McCusker.  It was a simple chapter book.  Using the "Imagination Station" and not magic, the kids travel through time on one great adventure after another.  The prologue gives the previous 3 books adventures in a summary that leads up to this book.  Though the adventure ends, the book sets itself up for another adventure for the cousins.  Though a simple story there is an educational/historical lesson about knights and jousts of peace.  The kids have to fit into the time perios so they ask questions, lending itself to an educational story that doesn't seem educational.  Not much of a Biblical message, though the children pray with Sir Andrew and good triumphs over evil.
