Frankly an excellent story from a debut novelist. It is always such a pleasure to reach the end of a book with a glow and a deep desire to immediately read the next volume. Thankfully, it appears the sequel (Mosaic) is already well underway!
Polaris follows two groups of characters living in starkly different worlds. Arthur, an art student and the main POV character, deals with university life and is recruited by a friendly-yet-mysterious character to help in 'Starside', a shared virtual space, that can only be entered while sleeping with a hacked brain implant. The second, the 'Fragment' stories, scattered throughout the novel, follow a broken wanderer through an apparently post-apocalyptic society.
A few things struck me about this book in particular. First, is the evolution of the worlds in both storylines, particularly what we learn about Starside, the technology of the near-future society that enables it, and the growing conspiracy around the brain implants. Both worlds FEEL different in a visceral way from the prose alone. The characters feel real and the worlds lived in and believable. If you've ever been or known college kids you will probably find some common ground here.
The second is the how genuinely inventive several aspects of this story are, along with a refreshing remix and twist on many sci-fi dream/brain implant/VR and fantasy tropes. All of this while exploring some truly terrifying implications of both the technology in the books and technology in our own world. The last half of the book in particular kept surprising me as we kept unwrapping new, and frequently scarier, more unsettling, and straight up weird aspects of our humanity through the lens of Starside and beyond. To keep it minimal, we even begin to see evidence of a magic system growing, and one that (as a reader of A LOT of sci-fi/fantasy) I haven't seen anything like before.
I do have some minor quibbles: references to the contemporary internet and its role in the story sometimes feel unintentionally silly in quite serious moments, as do some of the drawings. Pacing of some sections in the first half. Some minor plot conveniences. Everyone inexplicably loves Arthur. Anyways.
All said, this is a fun book! The Fragment stories and their fantasy elements were a particular highlight. I've spent quite a bit of time now thinking how both worlds might be connected.
Hope nothing this crazy happens when I fall asleep next.. wish me luck.
