IN 1955, scores of members of the Cambridge Inter-Collegiate Christian Union entered into a longstanding Evangelical tradition when they committed themselves to overseas service with Anglican missionary societies.

Randall sets the students’ decision in the context of its day, and follows what became of many of them, and how their ministries around the world developed (Cambridge Centre for Christianity Worldwide, Cambridge CB3 0AA, email Polly Keen, pk262@cam.ac.uk, £5 including p&p).
