December 1917 is a photographic guide to the Halifax Explosion by noted local historians Janet Kitz and Joan Payzant. The authors profile locations in both Halifax and Dartmouth that were affected by the explosion, looking at the role of the explosion in the transformation of the two cities. Stories and anecdotes reveal the ways in which the explosion touched the lives of citizens, and original research brings to light new aspects of the explosion. The book is richly illustrated with more than 100 historic and contemporary photographs, many in full colour.
