That Self-Same Metal by Brittany N Williams

Sixteen-year-old Joan Sands is a gifted craftswoman and an exceptional swordsmith. So skilled is her technique that she is one of very few women employed at the Globe Theatre, directing William Shakespeare and his troupe of actors in fierce scenes of combat. Of course, it helps that Joan is blessed with the power to control metal, thanks to Ogun, head deity of all Orishas.

But when a pact between the ancient Yoruba spirits and Fae is broken, only she can save the streets of London from peril. Joan must find a way to defeat them in battle by herself . .

. Okay, perhaps her twin brother James, blessed with gifts from Oya, can be of some help! And, despite the simmering tensions of a love triangle between herself, Rose, and Nick, Joan has a community of people to protect and who will protect her in return.
