Like every good concert, the 64-book Kirov series has to have an encore at the end. And so it was made in a book creatively titled Encore. I mentioned in my review of the final proper installment, Journey’s End, that the overarching villains of the aliens and Ivan Volkov were dealt with in an anticlimactic, rushed manner. This hoped to give them proper closure in proper battles.
It did not exactly work. By this point there was no way for the series to conclude in anything but a screeching halt, and all the big set pieces here did was change their fates from “short and contrived” to “long and contrived.” Then again, “long and contrived” describes the whole series well, so (shrugs).
This is only for Kirov completionists.
