Little Red and the Big Bad Hood (джен)

Olivia Draper had been a good idea at first. She could pass for older than Tim could pull off while masculine and women really could get into places easier if they had a pretty face. With makeup and some stylish-yet-inexpensive clothes, Olivia could pull off most undercover ops. She was Tim’s Matches Malone.
Then Hood had shown up on the scene.
-----------------------------------
When Jason met Olivia, he hadn't intended to pull a Bruce and take the scrappy teen informant under his wing. She just kept showing up where he was doing business. He had no other choice than to keep an eye on her. And kit her out with armor so she wouldn't accidentally get shot. And make sure she was being treated fairly by her mysterious boss.
And, okay, maybe become her big brother.
