“Kress’s Sleepless trilogy proved that she was a serious writer, worthy of considered attention. Probability Moon only emphasizes that.” —Locus

“This book has something for everyone.” —VOYA on Probability Moon

“Kress has blended such a nice set of surprises and inevitabilities that you should learn and read and enjoy them for yourself. You don’t have to read Probability Moon to have a good time, but you’ll probably search it out anyway.” —San Diego Union-Tribune on Probability Sun

“Displaying a typically strong synthesis of Kress’ many gifts, the novel leaves the door wide open for at least one successor.” —Booklist on Probability Sun
