Set in the late 22nd century, Chronosphere is a science fiction series which follows the adventures of teenager Raffi and his friends Dario, Jonah, Lastara and Sal in the Chronosphere, the place you go when you've bought time out of time. Ex Tempora, the third book in the series, sees our heroes being pulled back to the Chronosphere, to save a time-reversed lover and to bring an end to an eternal religious war. Life has not been easy for Raffi and his friends since their escape from the Chronosphere, but when they return, they find a world very different from the one they had left. The previous rulers have left a legacy of bitter conflict and religious fundamentalism, and it's up to Raffi and his time-altered companions to uncover the true motives of those who now wield power. They'll encounter old friends and mechanised enemies on their journey. Sacrifices will be made and love lost and won, but will they be able to overcome the challenges and escape with their lives and minds intact?
