The Twin Trial - Mrs Catherine I Skala

Tellus twins Max and Vicky are sent to beautiful and exciting but dark and dangerous Mars to study there for two years. No Tellusian has ever been to Mars before and this is an adventure of a lifetime for the twins. They live happily with their host families, school and friends until they experience firsthand what life on Mars is really like for all the Marsons who live there. Suddenly the rather naive twins are drawn into complicated webs spun by the totalitarian government of Mars and the underground movement, silently active all over the planet. No one can be trusted anymore and the twins have to rely on themselves and each other to make decisions that are a matter of life and death.
