Reviews

Inspired . . . something of the poetry and visionary wildness of an author such as Jeff VanderMeer . . . enthralling and thought-provoking in equal measure.
*DAILY MAIL*

Intricately described . . . gently immersive . . . Baxter's scientific grounding will make you dwell once more on that chilling quantum idea that to exist is to be observed . . . if you've been following the series from the beginning, this last chapter will make you cry, all on its own.
*GUARDIAN*

One of the unexpected delights of the later Pratchett career . . . a novel that comes across as a love letter to science fiction itself, one suffused with a Clarke-like optimism about the future. Baxter, you'd guess, is saluting two old friends here.
*SFX magazine*

A fine and fitting testament to the work of one of our greatest and much-missed writing legends, and a reminder that in the likes of Stephen Baxter, British science fiction remains in safe-hands.
