The Paradox Paradox by Daniel Hardcastle 1 is a sci-fi comedy book (and as far as I can tell, his first fiction book). I recently got a chance to read the book courtesy of an ARC 2 from netgalley.com in exchange for an honest review of the book, so here goes!
The book itself is a science-fiction comedy, in many ways a cross between The Hitchhiker's Guide to the Galaxy and Doctor Who. The story, (largely) set in the 2700s 3, takes place in a galaxy where Earth is part of an interstellar union, and follows a motley crew of eccentric recruits who are working together to stop an evil time traveler from accomplishing his goals.
I'll start with the strengths of this book, of which there were many. The biggest strength, for me, was the humor. Daniel Hardcastle channels his inner Douglas Adams and the book (especially the first half) had me genuinely laughing out loud regularly. The book is very indulgent with its use of sci-fi tropes, using common ones to flesh out the world, but also pokes fun at them and satirizes the genre in a way that worked well. (For instance, all species in the galaxy speak English, but only because "Marvel's films were in English, all seven hundred of them needed to be seen before the new ones, and nobody likes a dub.") It uses a combination of pop-culture references and timeless references, blending together into a self-aware style of humor akin to Hitchhiker's Guide or Deadpool that especially delights long-time fans of the genre. He also extensively uses footnotes, sneaking all sorts of hilarity in there: I am, of course, a big fan of Pratchett-style joke footnotes 4, so this, of course, was a big plus. Overall, I'd rank Hardcastle as one of the funniest authors I've read, just below Adams or Pratchett, which puts him in great company.
Now, lots of books are funny. What elevates this book beyond just a comedy is that, unlike Hitchhiker's Guide, this book actually has a plot and characters. Indeed, I was pleased to find that the characters and plot—while funny—weren't simply vessels for a punchline. The two most important characters, in particular, I found to be quite interesting and well fleshed out. Each had a strong backstory, interesting and complex motivations, and an arc over the course of the story. They were both characters, who, while being different from me in many ways, I still related to in some respects, and they were both just fun to read about.
And now, for the less exciting stuff. While this book was good and had a strong plot and some good character work throughout, I did find the ending to be a little underwhelming, and there were definitely parts that held this book back from being even better.
I'll start with the wibbly-wobbly timey-wimey nature of the plot. As tends to always be the case, time travel stories are hard to write in an internally consistent manner. My general motto for time travel stories tends to be "don't think about it too much", but in this case I thought the time travel to be especially convoluted and inconsistent. The story didn't just follow one of the "standard" time travel paradigms, but mixed and matched aspects from lots of different approachs: playing with bootstrap paradoxes, alternate universes, Back to the Future-style timeline erasure, and so on. It, furthermore, used some key timey-wimey plot devices as key elements in the resolution of the story. The end result, ultimately, was that it was hard for me to get invested in the ending, and largely found the ending to be more convoluted than satisfying.
The other bit that disappointed me a bit was the character work. I know, I know, I just praised the character work. Yes, I did: but for two of the characters. The problem, however, is that there are more than two important characters. The book itself follows a whole group of people: around 5-7 characters that I probably should have cared about. Unfortunately, I simply didn't. Part of this was that (perhaps to handle the large cast of characters), the author chose to write out certain characters from big chunks of the middle portion, but that didn't work for me. One character I was quite invested in just kind of disappeared partway through the book, leaving my quite disappointed, while other characters re-became relevant at the end at a point where I genuinely had to stop and go "wait, who was this again?" And there was at least one character that was around for a majority of the book, but just didn't get much development, leaving me uninvested in anything they did. So yes, overall, the character writing for some characters left a little to be desired: had Hardcastle replicated the character work on the two most important characters to even one or two more characters, I think this book would have been closer to a 5 star (at least a 4.5 star for sure), but as it stands that's what held it back by the end.
Overall, I thought this was a really fun read. Had the story been nothing but Daniel Hardcastle's jokes, one after another, I probably still would have enjoyed it, but it did a good job of elevating itself beyond a mere comedy with some sci-fi set dressing. It's an ambitious time-travel story with a fairly large cast, and while it falls a little short of them, it does get most of the way there. It's funny, uplifting, and well-written, it put a smile on my face most of the way through, and I'm glad to have read it.
Once again, a big thank you to Daniel Hardcastle and netgalley.comfor providing me with an Advanced Reader Copy of this book.
