Here are excerpts from a sterling review:
Watch your back, Peter F. Hamilton. Kay Kenyon is muscling in on your turf. If The Entire and the Rose isn’t the most audacious and exhilarating epic SF saga to hit the racks since the Night’s Dawn trilogy, then I might as well throw in the towel and take up reading vampire romance trash like everybody else. The third volume of Kenyon’s dazzling and inventive series has an action-driven forward momentum that keeps the suspense taut through well over 450 pages of narrative. Having introduced her remarkable alternate universe and its colorful array of characters, both human and alien, in the previous books, Kenyon simply cuts loose, ratcheting the story’s action and dramatic tension right off the scale. If you still haven’t added Kay Kenyon to your reading lists, City without End leaves you without any good excuses to keep ignoring her. . . .
(And skipping to end for sake of spoilers here . . .)
There’s one more book to go here. City does have a sense of closure to it, but there are many questions that still need answers, mysteries yet unsolved. To think that Kay Kenyon has more to offer, in light of how much she’s given us in these stories already, is thrilling to contemplate. I really don’t know where she’ll go from here. And that’s more than enough, not only to keep me on tenterhooks for the next volume, but to have you jumping into book one the first chance you get.
