Counterattack — Sigmund Brouwer

Set at an experimental community on Mars in the year 2039-2040, Robot Wars features 14-year-old virtual reality specialist Tyce Sanders. Life on the Red Planet is not always easy, but it is definitely exciting. As Tyce explores his strange surroundings, he finds that the mysteries of the planet point to his greatest discovery―a new relationship with God. He talks about his growing faith and curiosity in a manner that kids can relate to as they are probably wondering some of the same things.
Book four, Counterattack, opens with Tyce and some of the Mars Project's staff captured in a prison; they end up in prison while carrying out a special mission on Earth. Tyce has to figure out a way to fulfill their mission and rescue kids―all before a world war breaks out.
