River of Teeth

Hippo western, hell yes! I guess it's the Wild South rather than the Wild West, which makes it no less awesome. Shady riverboat tycoon, non-binary love interest, bi-sexual/pan(?) slightly grumpy main character, pregnant (lesbian?) assassin,  genderfluid french con-person, complete disregard for gender norms and casually diverse set of characters. Magnifique! {Also revenge and violence.) Adorable and bad ass hippos feature, not just feral man-eating ones. Will most definitely be picking up second book in this series/universe.
