““The first time she saw Wren that week, at lunch with Courtney, all Cath could think was, So this is what you look like when you’re keeping a giant secret from me—exactly the same as usual. Cath wondered if Wren was ever planning to talk to her about … what their dad had brought up. She wondered how many other important things Wren wasn’t telling her. And when had this started? When had Wren started filtering what she told Cath? I can do that, too, Cath thought, I can keep secrets. But Cath didn’t have any secrets, and she didn’t want to keep anything from Wren. Not when it felt so good, so easy, to know that when she was with Wren, she didn’t have to worry about a filter.””
