From a #1 New York Timesâ€“bestselling author, a research expedition to an alien planet takes a treacherous turn for married scientists in this sci-fi fantasy.
As the first humans granted permission to explore Tslamaina, Etienne and Lyra Redowl should have been ecstatic. The planetâ€™s massive river valley is like no other in the known universe, with three intelligent species living along its watersâ€”a dream expedition for the geologistâ€“anthropologist duo. But the intolerable climate makes their research arduous, as does the growing tension between them. Fortunately, the husband-and-wife team are well prepared for their adventure, with a state-of-the-art hydrofoil and the assistance of the native inhabitants. But nothing could have prepared them for the dangers they encounter as they make their way to the riverâ€™s source.
