A must-read for Remender's fans or anyone thrilled by bizarre and compelling sci-fi. Starred Review - Booklist There is a lot of meat to this book. Plenty for everyone to like, or dislike. The dangers are real. People die. The worldbuilding is solid even though we're jumping through different realities. Each of those worlds pops off the page and has their own distinct look and feel. - Kirkus This is a solid adventure tale... - PW Grant McKay, former member of The Anarchistic Order of Scientists, has finally done the impossible: He has deciphered Black Science and punched through the barriers of reality. But what lies beyond the veil is not epiphany, but chaos. Now Grant and his team are lost, living ghosts shipwrecked on an infinite ocean of alien worlds, barreling through the long-forgotten, ancient, and unimaginable dark realms. The only way is forward, through the madness of the lightning sea-swamp and a futurepast trenchworld, where the Sons of the Wakan Tech-Tanka wage never-ending war on the savages of Europe! How did the Anarchist League of Scientists end up this deep in the onion? And, who among them sabotaged the Pillar?'
