Return to the world of Rivers of London in this first short-story collection from best-selling author Ben Aaronovitch. Tales from the Folly is a carefully curated collection that gathers together previously published stories and brand-new tales in the same place for the first time.

Alex Verus is part of a world hidden in plain sight, running a magic shop in London. And while Alex's own powers aren't as showy as some mages, he does have the advantage of foreseeing the possible future-allowing him to pull off operations that have a million-to-one-chance of success. But when Alex is approached by multiple factions to crack open a relic from a long-ago mage war, he knows that whatever's inside must be beyond powerful.

A weekly newspaper dedicated to the weird and the wonderful (but mostly the weird), The Stranger Times is the go-to publication for the unexplained and inexplicable. At least that's their pitch. The reality is rather less auspicious. Their editor is a drunken, foul-tempered and foul-mouthed husk of a man who thinks little of the publication he edits. His staff are a ragtag group of misfits. And as for the assistant editor...well, that job is a revolving door - and it has just revolved to reveal Hannah Willis, who's got problems of her own.

Jodi Taylor reads the long-awaited prequel in her Chronicles of St Mary’s series, as Dr Bairstow struggles to set up St Mary’s as we know it in a world still scarred by the ravages of civil war. Ever wondered how it all began? It’s two years since the final victory at the Battersea Barricades. The fighting might be finished, but for Dr Bairstow, just now setting up St Mary's, the struggle is only beginning. How will he assemble his team? From where will his funding come?

In 1942, Lawrence Pritchard Waterhouse - mathematical genius and young Captain in the US Navy - is assigned to detachment 2702. It is an outfit so secret that only a handful of people know it exists, and some of those people have names like Churchill and Roosevelt. The mission of Watrehouse and Detachment 2702 - commanded by Marine Raider Bobby Shaftoe - is to keep the Nazis ignorant of the fact that Allied Intelligence has cracked the enemy's fabled Enigma code. In the present, Waterhouse's crypto-hacker grandson, Randy, is attempting to create a "data haven" in Southeast Asia....

The year is 2050. The power of magic and the creatures it brings have returned to the earth, and many of the ancient races have re-emerged. Elves, Orks, Mages, and lethal Dragons find a home in a world where mana, technology, and human flesh have melded into deadly urban predators. And the multinational mega-corporations that run the world hoard the only thing of real value - information. For Sam Verner, living in the womb of the Renraku conglomerate was easy, until his sister disappeared and the façade of the corporate reality began to disintegrate.

Stephen Oakwood is a young man on the edge of this hidden world. He has talent and potential, but turning that potential into magical power takes money, opportunity, and training. All Stephen has is a minimum wage job and a cat. But when a chance encounter with a member of House Ashford gets him noticed by the wrong people, Stephen is thrown in the deep end. For centuries, the vast corporations and aristocratic Houses of the magical world have grown impossibly rich and influential by hoarding their knowledge.

English magicians were once the wonder of the known world, with fairy servants at their beck and call; they could command winds, mountains, and woods. But by the early 1800s they have long since lost the ability to perform magic. They can only write long, dull papers about it, while fairy servants are nothing but a fading memory.

Necromancer is such an ugly word, but it's a title Eric Carter is stuck with. He sees ghosts, talks to the dead. He's turned it into a lucrative career putting troublesome spirits to rest, sometimes taking on even more dangerous things. For a fee, of course. When he left LA fifteen years ago, he thought he'd never go back. Too many bad memories. Too many people trying to kill him. But now his sister's been brutally murdered and Carter wants to find out why.

Atticus O’Sullivan, last of the Druids, lives peacefully in Arizona, running an occult bookshop and shape-shifting in his spare time to hunt with his Irish wolfhound. His neighbors and customers think that this handsome, tattooed Irish dude is about twenty-one years old - when in actuality, he’s twenty-one centuries old. Not to mention: He draws his power from the earth, possesses a sharp wit, and wields an even sharper magical sword known as Fragarach, the Answerer. Unfortunately, a very angry Celtic god wants that sword, and he’s hounded Atticus for centuries....

In the 20th century Earth sent probes, transmissions, and welcoming messages to the stars. Unfortunately, someone noticed. The Galactics arrived with their battle fleet in 2052. Rather than being exterminated under a barrage of hell-burners, Earth joined their vast Empire. Swearing allegiance to our distant alien overlords wasn't the only requirement for survival. We also had to have something of value to trade, something that neighboring planets would pay their hard-earned credits to buy. As most of the local worlds were too civilized to have a proper army, the only valuable service Earth could provide came in the form of soldiers....

A girl's quest to find her father leads her to an extended family of magical fighting booksellers who police the mythical Old World of England when it intrudes on the modern world.

Jane Charlotte has been arrested for murder. She tells police that she is a member of a secret organization devoted to fighting evil; her division is called the Department for the Final Disposition of Irredeemable Persons - "Bad Monkeys" for short. This confession earns Jane a trip to the jail’s psychiatric wing, where a doctor attempts to determine whether she is lying, crazy, or playing a different game altogether.

The RiftWar is done. But a fearsome army of trolls and renegade humans, emboldened by the drug of destruction, has risen in strength from the ashes of defeat. There is one, however, who defies the call to battle....

Al MacBharrais is both blessed and cursed. He is blessed with an extraordinary white moustache, an appreciation for craft cocktails - and a most unique magical talent. He can cast spells with magically enchanted ink and he uses his gifts to protect our world from rogue minions of various pantheons, especially the Fae.
