Every Heart a Doorway was one of my surprise favorites of 2016, so when I heard there was going to be another book in the series I got really excited. Then, honestly, I got a little apprehensive. What if it wasn't as good, or revisiting the world cheapened it? Yeah, I'll admit it - sequels sometimes make me nervous. In this particular case I needn't have worried. McGuire didn't rehash the job she did in the first book, but rather added new layers on top of what she built. Or perhaps I should say she added new layers below, as this book plumbs into the murky world of the Moors, and the events that occurred prior to EHaD.
Before you even get into the alternate world of magic and horror you get to spend time with Jack and Jill in the "real" world. You meet their parents before the sisters are even conceived and follow them all the way through their childhood. McGuire did such a good job with this entire section I found myself marking pages to reread. She made this family so repellant yet realistic, like a less cartoonish version of the Dursleys. There is so much in here about family, and children, that was astute and worth the exploration. And without this grounding the story that follows wouldn't be nearly as rewarding.
I love the way this book is written - how it feels like a Grimm fairytale. The authorial voice and the illustrations both add style and depth to the book. The world-building was well done, as was the mood and tone. Character was another win, as I thought Jack and Jill both came to life on the page. I was sucked in from start to finish. As with EHaD my only true complaint was that I wanted more, especially toward the end. Perhaps I'm just greedy. Regardless, this book hit the mark for me again and again, and I heartily recommend it. You can read it as a stand-alone if you so desire, but then you'd be missing out on another great book. I'm looking forward to the third book in the series!
