The Horns of Ruin is a fun, rather frenetic steampunk adventure with a very kickass heroine. There’s a lot of fascinating ideas in the world-building — the gods and the way divinity works, the invocations which are based on stories about the divinities, the interplay between the three gods… It feels like a piece of a larger world, maybe a tie-in for a game. Eva refers to her spells as buffs at one point, even!
This doesn’t always lead to the best storytelling, and it is a very linear plot which just features Eva bashing heads in, then briefly recuperating before going off to do it again. But it has its charms, and I enjoyed the ride.
