From the bestselling author of THE GREATCOATS: seven war mages with dark pasts must come together to fight an unknown enemy – but the stakes are higher than anyone can imagine . . . and someone’s setting the seven up for a fall.

Picture a wizard. Go ahead, close your eyes. There he is, see? Skinny old guy with a long straggly beard. The hat’s a must, too, right? Big, floppy thing. Wouldn’t want a simple steel helmet or something that might, you know, protect the part of him most needed for conjuring magical forces from being bashed in with a mace (or pretty much any household object).

Yep. Behold the mighty wizard.

Now open your eyes and let me show you what a real war mage looks like . . . but be warned: you’re probably not going to like it, because we’re violent, angry, dangerously broken people who sell our skills to the highest bidder and be damned to any moral or ethical considerations.

My name is Cade Ombra, and though I currently make my living as a mercenary wonderist, I used to have a far more noble-sounding job title – until I discovered the people I worked for weren’t quite as noble as I’d believed. Now I’m on the run and my only friend, a homicidal thunder mage, has invited me to join him on a suicide mission against the seven deadliest mages on the continent.

Time to recruit some very bad people to help us on this job . . .

A novel that wears its anti-hero credentials proudly on its sleeve
Geek Dad
de Castell doesn't get bogged down in the philosophizing. He lets his characters express the complexity and themes of the book through a propulsive and very fast-paced plot . . . this would make for a perfect summer beach read
The Fantasy Review
If you enjoy fantasy with clever plots, witty dialogue and characters with a keen sense of humour, you should keep The Malevolent Seven on your radar
A march through mayhem. A unique mix of murderous mages, polymorphic angels, cunning demons, found family, and much more . . . one of my favourite books of the year, no question
This is de Castell without any restraints and writing complete chaos. It was a pleasure to read
Just Geeking By
A great time with bad people. The magic is fun, the cast is funny, and the quest is hopeless. I highly recommend you strap in and watch this diverse cast of rogues fall upward toward their goal with as much cursing and calamity as possible
