Triggernometry Finals

"A little knowledge can be dangerous, but a lot of it can be deadly. We learned that the hard way."

Professor “Mad” Malago Browne – thief, killer, and one of the most wanted outlaws in the Western States – is trying to forget her bloody past and fight back against the tyranny of the Capitol, one maths lesson at a time.

The only problem? Gold talks and mathmos everywhere are listening, selling their skills – and each other – to the enemy for the price of freedom. There’s only one person with the power to stop them: Browne’s old mentor, Carl “the Cannon” Gauss.

But when tragedy strikes, it’s up to Browne and a rag tag faculty of numerates and renegades to do the impossible: unite the mathmos and bring the fight to the Capitol’s door, one last time.

Little do they know the eleventh hour might arrive sooner than they think…

Triggernometry Finals is the third and final instalment in the Triggernometry series, mixing the grit of the Western with a cast of mathematicians from across history to create a unique and explosive adventure.

Praise for Triggernometry #1:

“Full of Stark's trademark captivating imagery and lyrical prose this is another delight to digest... a gloriously fun ride through a shockingly familiar alternative history." - Fantasy Hive

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

“Like Holborn’s previous Western, Nunslinger, the real virtue of Triggernometry is how it ascends past its catchy pulp premise, and uses its charming concept to deliver complex characters dealing with murky moral problems.” – Tor.com

“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
