"There is a very rare and special pleasure that comes from reading a beautifully written book from a true expert in his field. In reading Walking on the Sea of Clouds, it immediately becomes apparent that Gray Rinehart is intimately familiar with the field of near-future space exploration. He understands what it will take to get mankind to the moon and beyond. He writes about the military as only someone who has been in the military can. He writes about bureaucracies and funding in the way that someone who has struggled with them does. When it comes to astronauts and space exploration, his characters ring undeniably true. He understands that some people are motivated to give all that they have in order to go into space simply because he has devoted so much of his life to this great endeavor.
"This book will be treasured by anyone who has ever dreamt of visiting the Moon, walking on another world, or bathing beneath the light of a distant star."
Charles E. Gannon:
"You’ve always wanted to go to the Moon. You’ve always loved hard science fiction. You’ve always gravitated toward believable characters. You’ve never found a way to get all three in the same place, at the same time. Well, now there’s a way. Here’s how:
"You pick up Gray Rinehart’s Walking on the Sea of Clouds, the most faithful and gritty 'you are there' novel of early lunar settlement I’ve ever had the pleasure to read. This is hard SF at its hardest—by which I mean that not only is the science spot on and largely off-the-shelf, but the characters conform to the emotional and psychological limits of folks we interact with every day. There are no galactic crises to be overcome, no interpersonal conflicts that erupt into homicidal rage, and no cast of quirky tycoons, femme fatales, or wise-cracking test-pilots. This is the Moon as it's likely to be in the early days of colonization, where even the smallest problems have impacts far beyond what living on Earth has trained us to anticipate.
"Annoyed you haven’t been to the Moon yet? Then pick up Walking on the Sea of Clouds; you’ll feel like you’re there."
"Two things are immediately clear. First, Gray Rinehart knows his field(s) inside out; and second, he writes with grace, skill, and professional polish. What more could any reader ask?"
"Gray Rinehart knows that real engineering is messy, and that Murphy was an optimist. When whatever can go wrong with constructing the first Lunar colony does go wrong, teams on the Moon and on Earth struggle to save the project--and their lives. This is meat and potatoes for the hard science fiction fan."
-- Martin L. Shoemaker, award-winning author of “Today I Am Paul”
"From the science to the science fiction costume party to the one scientist's African accent, everything about Walking on the Sea of Clouds feels amazingly authentic. They say an author should write what he knows, and based on this book, I'd say that Gray Rinehart has been in outer space, walked on the moon, thrown up in a NASA-approved barf-bag, fired thruster engines, and driven an LVN (gotta read the book if you want to know what that last one is). You can experience all that and more for yourself, too; just jump in on page one and don't stop until you get the end (like you could possibly stop once when you get started)."
