Characters: 9/10
This book is basically a masterclass in making you emotionally attached to fictional people (and non-humans) way too fast. Linus Baker starts out as the quintessential rule-following bureaucrat, and by the end, he’s a whole different person—in a way that actually makes sense. The kids? Absolute scene-stealers. Every single one of them has a unique personality that sticks with you. Arthur Parnassus is suspiciously perfect, but I’ll allow it. My only minor gripe? A few side characters felt a bit like cardboard cutouts, but honestly, I didn’t care because the main cast was that good.
Atmosphere/Setting: 8.5/10
If this book doesn’t make you want to run away to a cozy little island filled with magical misfits, then I don’t know what will. The setting is whimsical but never veers into being sickly sweet. The orphanage itself is vivid, and the world-building balances the mundane with the magical in a way that feels grounded. That said, Linus’s workplace felt like the equivalent of eating plain oatmeal every morning—not exactly riveting, but it serves its purpose.
Writing Style: 8/10
Klune’s prose is charming, snarky (which I appreciate), and effortlessly engaging. The humor is on point, the dialogue is snappy, and the narration has that slightly dry wit that makes everything feel a little more alive. However, there were moments where it leaned a bit too hard into the quirky, feel-good vibes, making some scenes feel a little... polished for reality. Still, it's easy to read and super effective at getting the emotions across.
Plot: 8.5/10
Look, you’re not getting a shocking, edge-of-your-seat thriller here. This is more of a cozy journey where the biggest tension is whether Linus will learn to have a personality outside of his job. But somehow, it works. The pacing is steady, and the stakes feel personal rather than world-ending. A couple of twists are predictable, but that’s not really the point—the heart of the story is in the relationships and growth, and that part delivers.
Intrigue: 9/10
I wasn’t glued to the book because of the plot—I was hooked because I needed to see how these characters’ lives would unfold. Every interaction between Linus and the kids pulled me in, and I was genuinely invested in how things would turn out. The mystery surrounding Arthur kept things interesting, even if it wasn’t the most shocking reveal in the world.
Logic/Relationships: 8/10
For a book about magical children and a government department with shades of dystopian bureaucracy, this actually held together really well. The relationships felt earned—Linus’s slow shift from skeptical rule-follower to fiercely protective dad figure was beautifully done. Some world-building elements, especially regarding how society treats magical beings, could have used a bit more depth, but overall, nothing threw me out of the story.
Enjoyment: 9/10
This book is like a warm hug, a good cup of tea, or petting a cat that actually likes you. It’s funny, heartfelt, and uplifting without feeling saccharine. Did I tear up? Maybe. Would I recommend it? Absolutely. If you want something hopeful with just the right amount of emotional gut punches, this is your book.
Overall: 8.6/10
This book is great. Not flawless, but it hits all the right emotional beats. If you love found family, dry humor, and a bit of magical whimsy, you’re in for a treat.
