Gideon the Ninth

Tamsyn Muir's necromantic science fantasy debut Gideon the Ninth is the most fun you'll ever have with a skeleton.

Somewhat reminiscent of Gormenghast but with skeletons, lesbian necromancers and one very cool protagonist (see cover).
Despite the story revolving around death - necromancer nobles are called upon to go through a series of mysterious trials in a haunted gothic palace to become the new servants of the deathless Emperor God - the plot is filled with life, energy and a rather peculiar kind of humor.
For those who like their space opera (or epic fantasy that happens to be in space) with a twist and slightly on the weird side.
I liked it. Liked it a lot.
