The first review of The Last Reef is now online at The Fix, and it's positive. The reviewer, Rae Bryant, writes:
"In The Last Reef, Powell holds a cross-section of science, nature, and technology in his quintessential human hand and gives it a roll across the universal table. What turns up is an eclectic mix of possibility, tragedy, and hope—a gamble worth betting on."
And:
"Powell’s depth and breadth of characterization work, and his settings are truly impressive. His work displays a willingness to show truths and flaws for what they are, rather than gratuitously exaggerating only strengths. With his instinct for subtlety, Powell is an author to watch. His work is the spyglass of science fiction, the ship just over the horizon."
