Endryn Kingdotur swore off echo-weaving a decade ago, because being able to hear the past is worthless if you don’t have the power to change it.

But when Bryn, the orphaned girl she is assigned to care for, goes missing from the underwater city of Ristaborg, Endryn breaks her rule to investigate.

What she finds is a set of mysterious voice messages addressed to her in the sea, left by a man she’s never met, but who knows her name and where she is going even before she does.

Determined to find Bryn, Endryn follows his lead into a world she once dreamed of exploring, unknowingly falling into a tangled knot of past, present, and future moments she may never unravel.
