With Necessary Evil, published today, Ian Tregillis triumphantly concludes his astonishing, brilliant, pulse-pounding debut trilogy, The Milkweed Triptych. Milkweed began in 2010 with Bitter Seeds, an alternate history WWII novel about a Nazi doctor who creates a race of twisted X-Men through a program of brutal experimentation; and of the British counter-strategy: calling up the British warlocks and paying the blood-price to the lurking elder gods who would change the very laws of physics in exchange for the blood of innocents. These elder gods, the Eidolons, hate humanity and wish to annihilate us, but we are so puny that they can only perceive us when we bleed for them. With each conjuration of the Eidolons on Britain's behalf, the warlocks bring closer the day when the Eidolons will break through and wipe humanity's stain off the universe.
Book two, The Coldest War, came out last summer -- a too-long hiatus! -- and jumped forward to the 1960s, where the struggle continued in a Europe divided among the Soviets -- who seized the Nazi technology at the end of the war and used it to breed their own supermen -- and the British, whose warlock reserves have become an everyday instrument of foreign policy. Coldest War was half James Bond, half Cthulhu, and was every bit as painstakingly researched, beautifully described, blisterlingly plotted and utterly engrossing as the first.
Now, with book three, Necessary Evil, Tregillis draws the series to a close with a time travel story that goes back to the beginning of the tale, a desperate mission to stop the use of magick and the use of the Nazi "Will to Power" from ever gaining hold, to keep the elder gods at bay. And in Evil, Tregillis is even more on form. This is a book that veers precipitously from unexpected and chilling ruminations on the inherent evil of precognition; to the questions of loyalty and betrayal so thorny that they need a time-travel loop to really be explored; to spy-thriller action sequences that will keep you up under the covers with a flashlight, turning pages and unable to sleep.
This is a remarkable set of books, and with all three in hand, would make a fabulous spring read.
