The Taexali Game

When the Rubidium Time-Leap flips Aran, Brian and Fianna back to AD 210 the reality of the game is incredible. They have a task list to fulfil, which includes solving a local mystery, but it's petrifying when Ancient Roman Legions heap death and destruction on the Taexali Celts of Caledonia. 

Giving help to Taexali and Romans alike becomes a lethal assignment - some Celtic chiefs are as foul as the Ancient Roman Emperor Severus and his beastly son Caracalla. Dicing with death becomes the norm for the time travellers. 

Will they complete the mission and return home unscathed?
