Thar be spoilers here
I thought it was particularly unusual that I couldn't hate the parents despite the fact they screwed up so much and did some awful things. You can tell they love their kids and want what's best for them, they're just so flawed and don't really know what's actually best for their kids sometimes (most of the time?)

The two parts that probably got to me the most was 1) when her dad asks her what she wants and she wants him to stop drinking and 2) when Lori quietly breaks down after they find out the money they saved up for New York is gone.
Glad all the kids seem to have made it out okay, even Maureen who near the end went off the deep end but the end of the book seems to indicate she's doing okay now.
