– Josh McDowell. Tyndale, 1991.
This small book is one of the most versatile items to put on your shelves. McDowell presents Christ as Lord and Savior with the utmost clarity, yet also dispenses with the myths and negative attacks against Him. You can read this in about an hour. Also, excellent as a giveaway.
