What would you do if, through an unexpected twist of fate and time, you came face to face with Jesus of Nazareth? In the flesh. A living, breathing, three-dimensional figure with a disconcertingly casual manner. Leo Resnick, a smart young Manhattan lawyer, and his girlfriend, Dr Miriam Maxwell, are confronted with this very reality. Leo's record of his encounter with The Man is fast-paced and thoughtful at the same time. Here Tilley showcases his ability to explore vast themes whilst creating a page-turning level of excitement. If you've ever looked up at the stars and wondered what it all means, this is the book you've been waiting for.

Mission, first published in 1981, is a sci-fi novel of biblical proportions full of wit, theology and - in an inspired twist - aliens.
