Wow.
'Tainted Universe', the third book in the Wanderer's Odyssey series, is a big step up from Goodson's previous offerings. The crew of the Wanderer continue their quest to travel to their ships' origin, unaware the the human empire is under attack from an enemy that spreads like an infection, an enemy known as the Taint.
It's possible to read this book without reading the previous volumes. Goodson does a nice job catching up new readers in the opening chapters. This book also contains multiple story threads, threads that allow the reader to appreciate the threat posed by the Taint, long before the crew of the Wanderer encounters it. There are space battles both large and small, plus an epic battle in cyberspace that's a real page turner.
I have two criticisms worth mentioning: 1) There are established characters who are suddenly filled with anger and paranoia. I actually suspected for quite a while that these behaviors might be early symptoms of the Taint. (They're not) 2) There are a few too many secret weapons and technologies that pop out of nowhere, giving the reader no opportunity to anticipate their use.
This is definitely NOT the last book in the series. The end of the book is a massive cliffhanger. The resolution of that cliffhanger is sure to catapult the story arc into new territory. My only frustration is that as I write this, it's been less than a month since the publication of 'Tainted Universe'. I'm going to be waiting a while for the next volume.
** 2020 Update **
It's mid 2020, and I recently read books 5 and 6 of this series. After six years the details of the first three books had grown fuzzy, so I just re-read them. Although books 5 and 6 have a few problems of their own, they did "fix" some of the issues I had with the first three.
