What is the family's situation in the bone and the sparrow book?

The story Bone and marrow talks of people without a family setting, children who do not have what they desire that have been lost into a cruel world.

Surbhi a refugee who has born in the camp that has no life of his own that only dreamt of fortune coming his ways. Jimmie also lost her mum and finds herself also in the camp they both hook up and writes their future. The family setting here looks like an illusion to the struggling surbhi, and the family situation is such that is pitiful as no one could stand as a family for the small children.
