In this gripping conclusion to The Alliance, nearly six months have passed since Leora Ebersole's Old Order Mennonite community fled to the mountains for refuge after an attack destroyed the region's power grid and altered life as they knew it. Since then, Leora has watched and waited for news of Moses Hughes, the young Englischer pilot who held off invading looters long enough for everyone to escape. Unsure Moses even survived, Leora has begun to warm to the affections of Jabil Synder, who has courted her patiently. But she struggles to see herself as the new bishop's wife, especially when she learns that Moses is alive and has now joined a local militia.
An unexpected encounter in the woods deepens Leora's crisis, as does a terrifying new threat that brings Moses's militia into the community's shaky alliance with the few Englischers left among them. When long-held beliefs are once again put to the test, Leora wrestles with the divide between having faith and taking action. Just how much will her shifting landscape change her?
