I feel like we need some sort of back story on Anna. It doesn't make sense that she'd somehow know all these people and how she'd be able to do so much volunteer work and afford covering two people's living expenses. Insight into her career would help, and back story to the girls as well.
Those additions would definitely help the story grow.
I love this story, so much! And I'm so intrigued by Sydney as a character. I'm very interested about her past and how it will change her future relationship with Vic... Can't wait for more !
