Good read
Format: Hardcover
This book has been getting a lot of hype, and I can understand why. First, it is a very unique storyline. Very different plot. Second, the main character, Natalie, is totally unlikable. In fact, I would honestly say I loathed her. She has no likeable qualities whatsoever. I guess that is what makes you want to keep reading, to find out what happens to this nasty woman. That said, I admit I was confused at the end. I am still not sure what exactly happened to Natalie, how the situation came about, and how 10 years went by when Natalie seemed to only be telling a few months time. Was she delusional? Did she have a mental breakdown? I wish it was more clear as to what exactly happened.

What did i spend so much time reading??
Format: Kindle
Spoilers ahead This book makes me angry. A misogynistic fable that holds women as mothers as inherently either deeply flawed or as if some fairy tale perfect mother exists. I found the early parts of the novel quite funny. Thinking this poor woman why do people expect such crazy standards? Also social media influencers somehow we are to take for reality? It is entertaining and that's why we want to spend our time looking at it. It is a fantasy world. Yet that is somehow turned from something comical and poignant dissolving into madness where there can be a 16 year old that can take away your children for what I'm not sure. Filming them? Having nannies? And then again the next bunch for living off the grid? I get that this isn't going for realism. It ultimately became for me this poorly written satire maybe? Obviously what started as comically intriguing for me descended into one totally crazy crazy turn to the darkest of places. I recognize this was supposed to be some sort of cracked fairytale where nearly everyone is evil and/or mental but 30 years for child abuse? This is like a nightmare not a thriller. The book demonstrates a hatred for mothers. Just awful! It made me crave for a totally unrealistic thriller. I came to be entertained and left pissed off.

Excellent satire of tradition cult
Format: Kindle
I read this book in two days. I was eager to read it once I read the description in a Facebook post. I am a theologically conservative Christian frustrated with the tradition culture that has co-opted the faith. I see this in my social and social media circles quite a bit, and I was intrigued by a novel that took this movement to task.
Furthermore, I truly enjoy well done satire and farce. I have had a hard time finding these works written well in the past, so I was bracing myself to be disappointed. I am thankful to say, I wasn’t. I didn’t expect the novel to go the way it did (and no, I won’t post spoilers), but I literally laughed out loud a several points.
Let me compliment the author for one particular point: She doesn’t just blast the “tradwife” movement. Plenty of cultural movements and groups of people have their sins exploited. Rather than shooting a 12-gauge at religious conservatives, she takes a Tommy gun and hits a wide range of systems.
I do want to warn squeamish readers about another issue: The novel can be quite graphic at times, explicitly detailing the intimacy struggles with the main couple. It borders on the pornographic side, but not for titillation. It’s meant to show the dysfunction in the supposedly happy couple.
There were quite a few humorous moments, such as the protagonist enjoying the sounds of the chickens, only to grow wistful about their impending deaths so she can taste chicken broth. Or the protagonist’s evangelical mother reacting to her son-in-law’s purchase of a yoga mat.
I was a little disappointed in the resolution of the central issue, i.e., the time travel. But overall, the novel was an enjoyable read and worth your time.

What did I just read
Format: Kindle
I’m not sure how to articulate my feelings about this book. It took me a bit to get into it, the story was interesting from the beginning but felt very slow paced to me. That changed about half way in. I don’t know what I was expecting, but that was not it! I did end up enjoying this. It was well written, funny, and shocking.

Let's go!
Format: Hardcover
This book is a classic! We purchased for our graduating senior and had all of her former teachers and coaches sign it with a special message on the pages. Great idea for a wedding or baby shower too. The quality is great! Love Dr. Seuss!
