I wasn't sure I wanted to spend a credit for the Audible only Terminus. I loved 14 and The Fold. I disliked Dead Moon so much I returned it. I'm so glad I listened to Terminus. It fit right in with the first 2 books. There were two returning characters and mentions of several others. The series is a tech thriller with some romantic elements and subtle humor. There's no use me trying to re-hash the plot of the book since it won't make any sense without going into the first 2 books. The books need to be read in order. I was totally engaged during the entire audio and recommend the series to those who like H.P. Lovecraft and thrillers. Or, if you enjoyed the TV series LOST............the plot isn't anything like LOST but the suspense twists and turns are as well as the interesting characters. The mystery pulled me in completely.
