In the Name of a Child (гет)

Barba hasn't been sleeping well, and his insomnia brings him into the life of a young girl desperate for a home and a family she can call her own. This chance encounter will change his life forever.
I wasn't going to write this when the idea first came to me, because I just wrote a story about Barba fostering a child and this plot felt too similar. In the end I decided I wanted to write it anyway, and even though it centers around Barba it's actually more about Liv, anyway. So happy birthday to Michelle even though this isn't any of the fics she actually wants me to write.
Also, Elliot Stabler does make a brief appearance in this, but I didn't tag him because I didn't want to. As always, he's getting no happy ending here.
