One of the best family dramas I know of is the wonderful book by Mary Lawson called Crow Lake. Mary, an ex-pat Canadian, now resides in England where she's raising her children with her husband.
Crow Lake is Mary's first novel. It is set in northern Ontario and describes what transpires to a household of four kids when their parents die in a car crash. The 17-year-old 'head of the household' decides to raise his siblings on his own.
Read Crow Lake. You'll be moved by the experience.
