Trek Lit Reviews has a review up for “Star Trek: Voyager: 15 Echoes”:
Echoes opens with a vivid scene: billions of people suddenly flash into existence in empty space, immediately exposed to hard vacuum and struggling to breathe. The struggle doesn’t last long, however, as the billions die an excruciating death in the dark cold of space. It’s an exciting (albeit incredibly dark) hook to immediately get the reader into the story!
