I have just recently stumbled across this show, and this is really good. I never thought I would like this just by it's description and name, but they can be really misleading in that way that you have to watch it to be able to determine if it's for you or not.
I keep wishing that there were more episodes to watch, but unfortunately there is none.
The service Callie and Mariana did together to help other Foster kids can be found from here: http://fostandfound.org. That's the information portal.
