I finished the 5 book Infinity Engines series by Andrew Hastie. Overall, I really enjoyed this series. As I said before, if you enjoy history you will like these books. I liked all the characters. I found them interesting and their stories compelling. As to the last book, Tesseract, while I enjoyed it, mainly because I was attached to the characters, I was slightly let down by the last third of the book. Without giving any spoilers, the plot started to remind me too much of the film Stargate. Now, I enjoyed that film, I really did. But I was afraid this book was going to lean too much on that film. I'm pleased to say that it got itself back on course by the end, though.

Loved it

What a thrill! I couldn't wait for this book to come out to see how things went. The ending felt a bit rushed, but still very satisfying. Overall with the story I still have questions about their version of time travel, such as how are there now thousands of versions of each person traveling the timeline? Not that it matters to enjoy the story. You have to let go of some of those questions and just go with it. I hope Andrew continues the series, although this arc is complete.

So much of this book could have been ripped straight out of Stargate. The wormy parasite may as well be one of the Goa'uld, the parasite using a human host, the leaders pretending to be Egyptian gods, etc. It's just lazy.
Inaccurate use of homonyms again, which has been a problem throughout the series - the editor needs to learn the difference between 'taught' and 'taut', for a start.

Another

Another fine example of runaway suspension of disbelief. A few years ago I would not have believed that I would enjoy such a book, but when you ease into it by reading the whole series, you prepare yourself for some really wild stuff. I enjoyed it immensely!

Mind Blown

I want to explain why I can't write more beautiful, intelligent, exquisite words for these books. They take you to places that you thought never existed, or perhaps you thought you couldn't believe. All that history. Free your mind.

A refreshing change to the genre, with characters who you will remember. I hope the last book lives up to expectations.

The problem with crushing these things back to back is that they all become one big story, but it's NOT a problem because the story is great.
