"Costambeys, Innes and Maclean are to be commended for having fulfilled their task [to provide a new synthesis taking into account the insights of the most recent scholarship] admirably, surveying and synthesising a vast body of source material and scholarship and presenting it with elegance and clarity … heartily to be recommended as a one-volume introduction for students and a useful work of reference for seasoned scholars."
Shami Ghosh, Reviews in History (history.ac.uk/reviews)
"Costambeys, Innes, and MacLean have provided an accessible and up-to-date survey to specialists and students of the period, as well as to interested lay readers."
