Seattle. Humans have no idea about witches or gods.
Beckett's a screw up. She's never been good with magic. What's a witch to do when she's more of a nuisance to the coven than she is an asset?
She goes on her own, makes a living working at a bookstore, and keeps trying to make her magic work.
It doesn't.
Finnick's a pain in the ass demigod who made the mistake of pissing off the wrong witch. Now he's carrying a curse. He needs a witch to break the curse. Too bad he's picked Beckett as that witch.
