For several years now I've been reading all of the Star Trek series books in order of release dates. That said, up to the point in which "Echoes" was released, with few exceptions, most of the Voyager books left a lot to be desired. That is certainly not the case with this book. "Echoes" is an extremely exciting book that at it's core uses the standard plot line - we're in the Delta Quadrant and we're short on this or that supply, we need to stop and find it - which has been pretty much worked to death by the previous "Voyager" books.
"Echoes" involves the Federation starship picking up some odd sensor readings, so they decide to investigate. Once Captain Janeway arrives, she and her crew are instantly involved in a tragedy so large in scale and magnitude, it seems almost unsolvable by one small ship. The residents of the planet have created a planet wide transporter system, and tied it into the planets core for power. This has disastrous results. Like clockwork, the transporter system kicks everybody on the planet over to the next "reality," "plane of existence." Where there's a planet, no problem, where there is not a planet, welcome to the vacuum of space. And so begins one of the more intriguing and better written numbered novels of any of the series!
I highly recommend this book to any and all Star Trek and in particular, "Voyager" fans. Thank you to the authors for another great Star Trek read.
