Like a combination of the Boxcar Children (absent parents) and Who Killed Cock Robin (environmentally driven plotline), but sometimes I felt as though the author was trying to tackle too many issues without satisfactorily resolving any of them.
I liked this quote...our protagonist is sitting up late with his youngest siblings waiting for his parents to finally arrive home:
p 263: "Bedtime caught up to Angus and Eva. Soon they were just staring. I'd watched them do this before--reach the end of the day with their eyes still open but with everything else all gone to sleep."
