The title of this post is a lie: I don't actually want to review Pratchett's
The Bromeliad Trilogy (also known as
The Nome Trilogy), but rather to gush over how great it is and to tell you all how it blew my mind when I was about 10.
I love this series the absurdly protective way reserved for childhood classics and I credit it with a big part of my interest in social change and activism. (I also spend a lot of energy aggressively trying to get all my friends to read it; and I would like to take the opportunity to ask you all to join the campaign for Claudia's education NOW).
The Nome Trilogy consists, unsurprisingly, of three books (Truckers, Diggers, Wings), and is, also unsurprisingly, about Nomes. Nomes are tiny people, about 10 cm high, who live on Earth unnoticed by humans. In Truckers, a group of outdoor Nomes, lead by Masklin and Grimma, find their way to Arnold Bros. (est 1905), a department store. There they meet the inside Nomes, who have lived under the floors of the store for generations and who don't react well to the unfamiliar (most inside Nomes hold the religious belief that ‘The Store’ contains 'All Things Under One Roof', and so there can be no “outside”, while the more scientifically inclined have devised the theory that outside Nomes would have pointy heads, as this shape is more fit for unpredictable weather). The outside Nomes have owned, since times immemorial, The Thing, a mostly useless metal cube. In the presence of the electricity in the store, The Thing powers up, revealing that it's the board computer of the ship that brought the Nomes to Earth, long ago. When they learn that the store is about to be demolished, the Nomes have to work together, navigating religious systems and social norms, as well as personal antipathies. They manage to escape the store in a truck, and find a new home at an abandoned quarry.
In Diggers, the Nomes have more or less adjusted to life in The Quarry, but they are continuously threatened by human presence. A religious sign prompts Masklin, Gurder (a religious leader), and Angalo (a prodigy engineer) to leave the quarry, going out to the investigate a nearby airport, taking the Thing with them. In their absence, those left behind have to deal with a new threat: the quarry is to be reopened. Grimma leads the defense efforts, sabotaging equipment, locking up the quarry, and even attempting to communicate with humans. In the end, the Nomes are driven out again, escaping on an excavator.
Wings is the story of Masklin's, Gurder's and Angalo's journey. The Thing convinces them that they should take it to a satellite launch, where it can attempt to contact the ship. The Nomes end up in Florida, where they meet other tribes of Nomes and realize there must be more to the Nomanity than they thought. Humans also have to deal with the existence of Nomes, as their spaceship lands. The Nomes use the ship to save the ones that are escaping the quarry, then leave Earth. But they know they must return, for all the other Nomes, as well as for humans, who might be capable of intelligent communication.
