Double Cross

Set in an experimental community on Mars in the year 2039, the Robot Wars series features 14-year-old virtual reality specialist Tyce Sanders. Life on the red planet is not always easy, but it is definitely exciting. Tyce 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. Each book contains two exciting adventures. In the first adventure of Double Cross, Tyce makes a startling discovery–one that could change life for everyone in the universe. That is, if Tyce lives to uncover the truth. In the second adventure, a deadly comet catapults toward Mars. Can Tyce figure out how to stop it before it destroys the colony?
Robot Wars is a repackaged and updated version of Mars Diaries. There are now five books in the series; each book contains two stories. These new books contain a foreword about how far science has brought us.
