Rounding out the trilogy with a rousing conclusion, The Armies of Daylight largely delivers. I don’t expect a major plot twist half way through the final book of a trilogy, but it worked well and made the final stretch a darker, more foreboding ride.
The saga continues (as does the in-story travelling, in spades). This is very much a Middle Book in which stuff is found out, additional civilizations feature to justify more worldbuilding and pieces are moved on (and off) the board in preparation for the grand finale.
This is traditional portal fantasy: two outsiders from our world are sucked into a conflict with an ancient, (literally) nebulous enemy in a parallel fantasy world. Darwath is losing the war, its King is dead, his heir a baby, and the political powers are at one another’s throats as they vie for control in spite of ongoing assaults. This first installment sets the scene and embeds the offworlders for (presumably) future glory.
