The Dusk Watchman by Tom Lloyd

Tom Lloyd’s The Dusk Watchman is book five in The Twilight Reign series (Gollancz £14.99), out later this month.

“After his pyrrhic victory at Moorview, King Emin learns the truth about the child Ruhen, but he is powerless to act. Instead, he must mourn his dead friends while his enemy promises the beleaguered peoples of the Land a new age of peace. The past year has taken a grave toll: the remaining Menin troops seek revenge upon Emin, daemons freely walk the Land, and Ruhen's power is increasing daily.

And yet, a glimmer of hope remains. There is one final, desperate chance for victory: a weapon, so terrible only a dead man could wield it, and only a madman would try. But if they do not grasp this opportunity, King Emin and his allies will be obliterated as Ruhen's millennia-old plans are about to bear terrible fruit. If his power continues unchecked, Ruhen will achieve total dominion and not just over mankind, but over the Gods themselves.
One way or another, the future of the Land will be decided now written in the blood of men.”
