I liked Containment, and Human Legacy Project was just as good. Brainbox was good, but the story itself was not very attractive to me. Now, if Containment and HLP were excellent, then Epoch Index was excellent to the 10th power.
In the other 3 Cantrell's that I've read, he has done a great job of 'creating' new technology, but in Epoch, what he did was 'explore' whole new branches of science. Epoch Index is absolutely amazing, and brings Cantrell to the level of Asimov, Card, Verne and Wells.
I always enjoy how his stories develop from events that are going on today, be it climate change, the shutting down of NASA, recycling, etc; but in this case he has completely outdone his other works by referencing the LHC and creating a whole new branch of science. I don't want to give away parts of the plot, but thank you Mr. Cantrell for bringing Science Fiction back to life, where it is not just cool lasers that are used, but where science is invented and created. The genre is called Science Fiction for a reason, although lately, most new SF works should fall under the 'Technology Fiction' genre. That has been truly disappointing to me, and I welcome the 'return' of good Sci-Fi.
The plot is unbelievably crazy and awesome (for lack of better words). The plot twists along with the alternating points of view make Epoch Index a story full of suspense and thrill.
I once again note how good Cantrell's endings are. They are hard to surpass.
The book description didn't get me interested in the book, as it didn't sound too much like Science Fiction. The cover looked interesting and having read Cantrell's other works, I knew I liked his style, so I choose to read it, and I don't regret it. Trust me, it is Science Fiction, and it is probably the best you will have read in a long time.
As with all of Cantrell's stories, this one is too short. Please make it longer! The story in Epoch Index is too good to be so short.
A great read overall, highly recommended.
