Hm. The story ended up being good - with a few caveats. 

The good:
It does have a lot of important things to say about women, motherhood, taboos of not liking certain things about motherhood, complete silence on dangers of pregnancy, working outside the home women, formerly working outside the home women and all that entails. Most of these were communicated in the main character's thoughts, though, just written out. Not nearly enough of these were shown rather than just told. The more concealing or convincing of these came through as she interacted with Jen vs her still working mom friends. 

And the bad:
At a little over halfway in, she kills their family pet, a cat. It's true that that wasn't celebrated and it was a turning point / get your life together moment for the character, but when you're maiming the family pet, you've crossed a line. Like abusers who start out choking girlfriends or killing their dog - just nope, i don't care what grand point you're making, i sort of stopped being entirely open to what this novel was trying to do at that point.

I also thought the animosity toward the cat they kept as a pet was kind of an odd choice (even when the mother was in human form). Yeah, i get that the mom's a dog, but it seems a bit cartoonish and silly to have a dog/cat rivalry or murder as though a dog is the top in the hierarchy next to humans and all other animals are to be exterminated. 

Overall:
It was just pretty good. I like the mythology and werewolf things, that meshing well with moms of young kids wondering what they've become in such a short time, the rage and the love and being transformed. It's good imagery. A magical grandma and possibly Amish sounding religion (maybe too specific, but the author's name is Yoder...), also nice touches. It's a good idea, just i don't know that it landed completely for me.
