This paperback, in the Christian Focus imprint CF4.K, appears to be aimed principally at younger teenagers. The questions about the Christian faith which it seeks to answer are Is it true?, Does it work? and Is it worth it?. The issues are approached through a series of potted biographies (with a strong Scottish flavour) of twelve Christians, ranging from St Columba through Knox, John Bunyan and Mary Slessor to the contemporary Joni Erickson. Randall makes a persuasive case for the inclusion of each of the above. They are chosen for their astonishing range of achievement and Christian character, notably perseverance in the face of extraordinary difficulties. While the biographies are very condensed, they cover the life stories fairly and do not skirt round the rough edges. It is good to see that CFP are also publishing fuller biographies of several of Randall's twelve under the CF4.K label. This is a worthwhile book, calculated to appeal to and inspire youngsters – and perhaps older folk as well. It will make a useful addition to any church library.
