BOOKCLUB - The Devils by Joe Abercrombie

Europe stares into the abyss.
Plague and famine stalk the land, monsters lurk in every shadow and greedy princes care for nothing but their own ambitions. Only one thing is certain: The elves will come again, and they will eat everyone.
Only the darkest path leads towards the light. A path the righteous will not dare to tread.
And so, deep beneath the sacred splendour of the Celestial Palace lies the secret Chapel of the Holy Expediency. For its congregation of convicted monsters there are no sins that have not been committed, no lines that will not be crossed and no mission that cannot be turned into a disastrous bloodbath.
When you’re headed through hell, you need the Devils on your side.
