“Crunch crunch crunch.”

Many of the world’s finest cities are built on grids: New York, Barcelona, San Francisco, Paris, parts of Edinburgh and much of Rome. London, however, is not quite like that. With so many dead ends, cut-throughs, alleys, curves and very little regulation regarding street naming, there’s a theory that it’s been built like that specifically to confuse tourists. Or maybe it’s just to slow down any army that returns to take its nations stuff back from the museums. Dream London take this to a whole new level, and as I’m really missing my visits to the capital this week, it seemed a good place to spend a little time.

Dream London is not the London we once knew. The city changes a little bit every night, and the people change a little every day. The parks have disappeared, the Thames is now an impassable mile-wide waterway, the towers are gaining new floors with alarming regularity, and you never know if you’ll wake up to find your house next to a pub or a train station, or even if your house still exists. No one knows why this is happening, and have even less idea of how to stop it. Enter, Captain Jim Wedderburn. A former soldier, he left the army and is now struggling to make ends meet in this twisted version of his old home. He looks after a cohort of prostitutes and does his best to keep out of trouble, but Dream London has a way of making you into someone new.

Wedderburn’s fame is large, and when two rival factions seek him out for help against one another, he finds himself torn in two. Does he follow the Cohort into the legendary Angel Tower, the thousand-storey skyscraper that seems to be the centre of the changes, or does he join Daddio Clarke and his army of captive followers who all possess eyes on their tongues and send foul-mouthed little girls in to do the dirty work? Elsewhere, Dream London has given Wedderburn his fortune and he learns that he will soon betray one of his friends, and another will betray him. There’s no escape, the parks are getting bigger – even if no one can access them – and something terrible is coming. But this is a city where nothing is ever the same two days running, so how on Earth can it ever be put back together?

With shades of Neverwhere and Jasper Fforde abounds, this is a riotous romp through a fictional London that still seems oddly familiar. This must be what it’s like to be a first-time visitor to the city, with roads and train stations that come and go as they please, an inconsistent skyline, and people everywhere only out for themselves. Dream London seems to slowly be sinking back into a place of Victorian values, where workhouses exist and women are relegated mostly to either selling sex or cleaning floors. It’s not a bad life for everyone, but it very much depends who you are. Ballantyne does amazing work at spinning this mythical city on the page and bringing it to life. The complications of trains that never take you where you want, least of all out of Dream London, the obsession with eggs of the people who live near the fabled Egg Market, and the astounding reveal of who is behind it all are strokes of genius.

One of my favourite inventions is the Angel Tower, which is hiring people to rewrite the laws of the universe. On the Writing Floor, whatever is written becomes fact and shifts the city into a new shape. Anything from here that then gets moved to the Contracts Floor is immutable and unchanging. The Numbers Floor is the most interesting, however. There are no prime numbers in Dream London, and so Wedderburn is hired to prove this. When looking at the numbers, his mind begins to be affected by the city and he realises that there are other numbers between the numbers we know. As of now, seventeen has always been two times green. This is beautifully followed with the chapter titles, which insert the colours (and one two occasions, mere sensations) into the running order. A madcap idea that is executed with true skill.

Sharp, interesting characters, a well-defined world, and some utterly believable silliness. What isn’t to love about this?

Did you know that as well as reviewing everything I read, I also write novels, too? My books blend black humour with light horror, crossing genres with ordinary characters dealing with extraordinary circumstances. Head over to wherever you buy books to take a look at my two offerings. The first, The Atomic Blood-stained Bus, introduces you to a cannibal, an ex-god and the last witches of Britain, while the second, The Third Wheel, follows Dexter who is tired of being single while all his friends get married and settle down, but has a change of priority when aliens invade the planet. I hope you enjoy!
