Okay, real talk: I picked this up because I was procrastinating on my thesis at 11 PM and needed something under 10 hours that wasn't going to demand I keep a spreadsheet of character genealogies. (My Stormlight reread is on pause. Dr. Patel would be thrilled if he knew why. He would not be thrilled.)
So here's my playful complaint before I say anything nice: April May is kind of insufferable. Not in a "I hate this book" way — in a "oh no, this is a real person I've definitely met at a convention" way. She's the person who goes viral and immediately starts believing the narrative about herself. And Hank Green — who, let's be honest, has watched this exact thing happen to real humans from a front-row seat on YouTube — writes it with this uncomfortable accuracy that made me put down my cold brew and actually stare at the wall for a second.
That's the thing about this book. You think you're getting a fun alien mystery. Giant samurai-armor robots appear in cities worldwide overnight, April stumbles across the Manhattan one at 3 AM, makes a video, and boom — she's the face of first contact. Cool premise, right? My D&D group would immediately start theorycrafting what the Carls want. But Green is way more interested in what fame does to April than what the Carls actually are. Which is either going to hook you completely or frustrate you into a two-star review. (The two-star camp exists. I get it. I don't agree, but I get it.)
The Carl Mystery Is Just the MacGuffin, and That's Fine
The actual puzzle — decoding what the Carls are trying to communicate — is genuinely clever. There's a recurring dream sequence mechanic where April and other people who've touched the Carls share this strange puzzle-space, and the logic of it scratches the same itch as a good D&D riddle. Not Sanderson-level magic system, but the rules feel consistent and the payoff of the puzzle itself is satisfying. What's less satisfying is that Green is clearly more excited about the internet-fame allegory than the alien lore, so if you came for hard sci-fi first contact, you'll feel a little starved by the end.
But the internet stuff? Genuinely sharp. The way April watches her own public persona split off from her actual self, the way online communities radicalize around her — for better and worse — it's the kind of writing that makes you close the app and scroll your own social media with slightly more existential dread than usual. Green's lived this. It shows. The only other book I've read recently that dissects identity and self-narrative with this kind of uncomfortable precision is Unbearable Lightness of Being — wildly different setting, same queasy feeling of watching a character construct a self and then get trapped inside it.
Kristen Sieh Does the Heavy Lifting (And Hank Shows Up for the Finale)
Here's where I will die on a hill: Kristen Sieh is doing serious work here. April May is written with this specific voice — confident but kind of brittle, funny but self-aware that she's performing the funny — and Sieh nails it without making April cartoonishly unlikeable. Her Miranda (the scientist character who keeps trying to ground April in actual facts) has this wide-eyed earnestness that reads completely differently from April's defensive wit. You always know who's talking. At 9.5 hours, that matters.
And then Hank Green narrates the last chapter himself. Which sounds like a gimmick. It is not a gimmick. There's something about hearing the actual author — someone who genuinely lives in this world of internet fame and has complicated feelings about it — read the final emotional beat that lands differently than it would on the page. It's the kind of thing that only works in audio. Kristen Sieh walked so Hank could jog in for one chapter and make you feel things.
Who This Is For (And Who Should Probably Skip It)
If you want a character study about a deeply flawed person navigating sudden fame, wrapped in a genuinely interesting alien mystery with a narrator who keeps the pace snappy — this is your book. If you need your protagonist to be likeable, or if you're here primarily for the sci-fi and want real answers about the Carls, you might bounce off it hard. The 2-star reviews are almost all "April is the worst" and "the alien stuff doesn't pay off enough," and those people aren't wrong about the facts, they just wanted a different book.
I listened to this instead of writing my thesis. I regret nothing. It's the kind of story that makes you think about your own relationship with the internet for like three days afterward, which is either a feature or a bug depending on how much you want to examine your screen time.
