Operation Bounce House

Matt Dinniman

Average Rating 9/10 (2 Reviews)

A man must fight for his planet against impossible odds when gamers from Earth attempt to remotely annihilate it in this epic, fast-paced novel from the New York Times bestselling author of the smash-hit Dungeon Crawler Carl.

All colonist Oliver Lewis ever wanted to do was run the family ranch with his sister, maybe play a gig or two with his band, and keep his family's aging fleet of intelligent agriculture bots ticking as long as possible. He figures it will be a good thing when the transfer gate finally opens all the way and restores instant travel and full communication between Earth and his planet, New Sonora. But there's a complication.

Even though the settlers were promised they'd be left in peace, Earth's government now has other plans. The colossal Apex Industries is hired to commence an "eviction action." But maximizing profits will always be Apex's number one priority. Why spend money printing and deploying AI soldiers when they can turn it into a game? Why not charge bored Earthers for the opportunity to design their own war machines and remotely pilot them from the comfort of their homes?

The game is called Operation Bounce House.

Oliver and his friends soon find themselves fighting for their lives against machines piloted by gamers who've paid a premium for the privilege. With the help of an old book from his grandfather and a bucket of rusty parts, Oliver is determined to defend the only home he's ever known.

Like a lot of good books, Dungeon Crawler Carl by Matt Dinniman was a personal recommendation by not one but three separate people, all of whom we respect on the book front. Having read the cover blurb, I was a little sceptical (LitRPG?) but being a fan of Hitch-Hikers, as well as the works of Christopher Moore and Chris Brookmyre, I thought I would give it a go – six weeks later I had consumed the first seven (very long) books and was hooked.

Searching NetGalley to see if the next in the series was available as an ARC imagine my joy on finding Operation Bounce House listed. I submitted my request and heard nothing for several weeks so had basically given up when a notification arrived, Approved! Many thanks to Michael Joseph's and NetGalley for the advanced reading copy provided.

Now, to be clear from the start, Operation Bounce House is not an LitRPG story as with the Dungeon Crawler Carl series – it is straight up Science Fiction novel with a game as the main premise – there are no stats, XP, level ups, loot, etc. This in no way detracts from the story being told but for the DCC fans it is worth noting because, for me, the cover blurb may lead you to believe otherwise.

Oliver and Lulu are brother and sister living on the colony world New Sonora. Oliver is a farmer and Lulu, when not farming, is an online entertainer. They are relatively content and looking forward to New Sonora being fully connected to Earth when events take a strange turn.

When a remote agriculture bot goes missing Oliver sets off to find it only to be attacked by a garishly painted Mech (war machine) that appears to be controlled by a child, a very spoilt child at that.

As planetwide destruction ensues Oliver learns, with the help of Roger, the Hive Queen AI, that the planet is the subject of the game Operation Bounce House, a Pay-to-Play, hunt the terrorist sub-humans and slaughter them all, game... only New Sonora is a happy world, there are no terrorists.

Now for the thorny issue. I can see some future reviews may bemoan that fact that this isn’t a LitRPG book like DCC, it is a straightforward science fiction story; in fact, if I had to classify a sub-genre, I would say it leans more to military SF. Don’t let any of that put you off, if you are a DCC fan you will love it. If you are new to MD it is the perfect place to start; but be warned, once you are under his spell it is very difficult to leave.

I really enjoyed Operation Bounce House. Matt Dinniman’s flowing style of writing and storytelling make his latest book a real delight to read.

Thank you to Michael Joseph's and NetGalley for an advanced reading copy.

Imagine if you were a settler in a frontier land, settled by your families who came on a big ship. You have all worked hard to carve out a life, and then someone comes along to take it all away and give it all (based on your hard work) to someone else. Imagine that it is a long-planned policy, send out the idealists and the criminals, let them travel for lifetimes to a new place and expend themselves making the land fit for corporate takeover. How would you feel? The whole of human history is littered with examples of covetous people wanting something that they have not built but can take by force and Operation Bounce House is an exploration of this theme (no political point scoring here, just an observation on history).

Ollie lives on a farm, he and his family have been there for a couple of generations, arrived on a ship, been working hard to make a living. Life has been hard, a lot of people did not live long lives, both adults and children, but they found a way to tinker a little so that the new generation could thrive. The technology that enabled their journey and initial settling has gradually failed due to use and planned obsolescence, but life rumbles on.

Ollie and Lulu live in the home built by their grandfather with Roger, the Hive Queen AI, who controls the last of the farm worker units whose charging cycles are becoming longer and whose useful life is coming to an end. So, when a drone does not come back one day, Ollie thinks it has failed, but it turns out to be due to something from off world, and it is followed shortly afterwards by a machine covered in punk designs which is heavily armed and treating the place like a shooting range. This is not the first, more come and the settlers are ill-prepared for the conflict.

It is a fabulous, hideous thought, to sell the opportunity to pilot a killing machine on a different planet, single players and clans, all are welcome, all are fair game; as a means of planetary clearance, a ‘making money via death and mayhem as entertainment model’ with the side benefit of clearing the current occupants. The settlers and Roger have to battle for their home, with old and new technologies. The extrapolated consequences of the use of stuff impacting our lives now are all up for consideration; our online lives, the manipulation of our available information, the use of AI, the use of propaganda and social media can be weaponised and are all exploited. For all the depths it plumbs, it is a rollicking good story, and like other MD books, I can honestly say I never notice how long they are, they carry you along, just marvelling at the events going by, building and building to the end. I do love his writing (in case you had not gathered).

We came to Matt Dinniman’s Dungeon Crawler Carl books via three well respected book fan friends, and luckily there was a hefty number already published that we ploughed through end on end, loving every madcap achievement. So, when we were offered the opportunity to read Operation Bounce House, we were delighted. I had not read the blurb before I read the book, and I have to say that the blurb, suggesting LitRPG, is a little misleading. This is science fiction, in a grand world building, generation ship, evil corporation fighting style, and I loved it.

I get that publishers like their authors to stay in their lane, to write what their fans have come to enjoy, makes marketing much easier, but it must be incredibly difficult to weave in an idea which stands apart from the usual canon, and the regret at not being able to explore outside their lane must be a creative person’s special itch. But like Iain M. Banks, and Jodi Taylor, sometimes authors who are given free rein come up with fabulous things, not in their lane, but adjacent. Operation Bounce House is one of those wonderful surprises, but it is not LitRPG, please do not be disappointed at the thing it is not, love it for what it is.
