Query: THE NEW MATT CHRISTOPHER!

Author Rich Wallace is everything Matt Christopher used to be -- and more! Wallace's characters are honest, funny and real. They are not perfect, like most of us. Protagonist Manny Ramos and his teammates talk like real kids. They learn their own lessons, teaching each other -- instead of waiting for an adult to solve their problems, as in the old-fashioned sports novels. Best of all, Wallace writes unmatched sports game action. Knowing that he'll be using the same characters from the same school and town, I'll be anxious to read the other books in this series.
