I was really frustrated with this book. It tried too hard to do too many things.

Loving parents secretly worked at Auschwitz? Check.
Secret childhood homicide? Check.
Dementia that leads to moment of clarity between father and son? Check.
Camp survivor that is actually just hallucinating and only has survivor's guilt for getting away to Canada in time and was never actually in a camp? Check.
Nurse sister that secretly has Munchausen's by Proxy? Check.

The author also tried to constantly shift perspective but in my opinion, did so rather poorly. It was often difficult to follow along with what was happening because it would change within a sentence from one character's viewpoint to another with no notice. Often these characters were in opposite sides of town and it might even be a different time of day. Their activities might be linked but might not and sometimes they looped back around within a paragraph, again with little to no signal to the reader that that would be occurring.
