Terry Pratchett & Stephen Baxter: The Long Cosmos

Hi everyone

Yesterday I finished the fifth and final book in The Long Earth series by Terry Pratchett & Stephen Baxter. This was my second time reading it, and while it wraps up the series neatly, I walked away with mixed feelings.

"2070-71. Nearly six decades after Step Day, a new society continues to evolve in the Long Earth. Now, a message has been received: “Join us.”
The Next - the hyper-intelligent post-humans - realize that the missive contains instructions for kick-starting the development of an immense artificial intelligence known as The Machine. But to build this computer the size of an Earth continent, they must obtain help from the more populous and still industrious worlds of mankind.
Meanwhile, on a trek in the High Meggers, Joshua Valienté, now nearing seventy, is saved from death when a troll band discovers him. Living among the trolls as he recovers, Joshua develops a deeper understanding of this collective-intelligence species and its society. He discovers that some older trolls, with capacious memories, act as communal libraries, and live on a very strange Long Earth world, in caverns under the root systems of trees as tall as mountains.
Valienté also learns something much more profound . . . about life and its purpose in the Long Earth: We cultivate the cosmos to maximize the opportunities for life and joy in this universe, and to prepare for new universes to come."

The Long Cosmos is satisfying in that it concludes everything nicely. However, it also feels disappointing because it lacks the drive and depth I’d hoped for in a series finale.
The book obviously aims for an epic conclusion and it just doesn't deliver. The last 100 pages, in particular, feel underwhelming, and the entire book is surprisingly uneventful. There are countless repetitions (and jokes) of how old the characters are, and while two characters go missing (how convenient!), we never truly uncover the purpose of the mysterious message or the supercomputer. It feels like a missed opportunity to explore something truly profound. 

Don’t get me wrong; The Long Cosmos is a quick and easy read. It’s never boring, but it also didn’t hold my attention for long stretches. In fact, it says a lot that this was my second time reading the series, and I barely remember more than the basic premise. The story just doesn’t leave a lasting impression, which is a shame for what could have been an epic finale to a series with a thought-provoking and interesting premise. 
As it turns out, the premise is the most exciting part of the whole series.

Have you read The Long Cosmos or any of the other books in The Long Earth series? Did you feel the same way, or did the finale resonate more with you? I’d love to hear your thoughts!

Happy reading!
