That gold you stole will burn a hole in your heart… Having pulled off the heist of the century, Professor Malago Browne and Pierre de Fermat are determined to hang up their protractors for good. But when you're the most notorious mathematician in the west, peace doesn’t come easy… When three women approach Browne with a proposition, she can’t help but listen. Terrorised by a corrupt sheriff and his posse, the town need to hire the quickest and deadliest fighters they can: in other words, mathmos. Together with six unlikely allies, Browne once again finds herself facing incalculable odds in a battle for the town, its people, and the fate of every mathematician in the Western States. And seven isn’t always a lucky number… The second novella in Stark Holborn’s series, Advanced Triggernometry mixes the grit of the west with a cast of mathematicians from across history to create a truly unique and unforgettable adventure. “Clever, funny, subversive, wholly original, and packs a bigger punch than a Colt Peacemaker.” – Joanne Harris, author of Homeycomb, The Strawberry Thief, Chocolat & many more Praise for Triggernometry: “A wild, rollicking and endlessly-surprising tale of low lives and higher mathematics. I loved it!” – Lavie Tidhar, award-winning author of By Force Alone , Unholy Land and Central Station “Totally unique and a veritable jolt to the sheer perversity of the imagination… It’s like Sergio Leone and William Gibson rewriting the Old West with a quantum calculator” – Maxim Jakubowski
