Read this book a time ago (3+ years ago) where this organization helps people fight off supernatural beings, I'm pretty sure they were evil spirits, but they fought them with their abilities, and they're always in partners, one with an active member and a passive member, each with different abilities (such as strengthened senses and energy powers i think), and only the leader of the organization has both passive/active. And the main character is one girl who,is an active member and its her and,her friends rooting out the corruption in the organization itself. Also I'm from the USA and it was in English.
Can anyone help me figure out the title and author of this book? Thanks so much.
