In the Midst of Alarms [EPUB ebook] 

In the late 1860s, typically peaceable Canada found itself under attack. The invaders were members of the Fenian Brotherhood, an Irish Republican group based in the U.S. In a series of raids that occurred over a period of years, hundreds were wounded and dozens were killed, and many historians believe that the attacks fomented anti-American feelings in Canada. This gripping fictionalized account of the raids offers a blow-by-blow narrative of the most significant skirmishes.
