"Palmgren manages once again to merge the world of comics and prose fiction perfectly in that their story reads like a comic in terms of action and adventure but has the wonderful add on of wider character development (we get to see what characters are thinking and feeling more clearly than in the comic verse) and the superb and frankly hilarious footnotes by our heroine, Squirrel Girl and her wonderful editor"

"Squirrel Girl: Universe is not your normal super hero story. Other than the inclusion of some super heroes, I wouldn't even include it in that genre. Instead, Tristan Palmgren has tried to do something different, and has crafted a weird and wonderful science fiction story that at times feels like it has more in common with something like The Hitchhikers Guide To The Galaxy than it does your average Spider-Man adventure."

– Trans-Scribe

"It’s wild, thoughtful, exciting, and of course, hilarious. The journey it invites you on contains the same level of cosmic wonder as virtually any Marvel movie, and whilst it might occupy one of the more outlandish segments of the Marvel universe, this novel is no less substantial for it."

– The Book Network

“This is Squirrel Girl at peak cleverness, peak brilliance, and peak hilarity. It's a thrilling adventure filled with big ideas explored in fun ways –Tristan Palmgren has truly captured the soul of these characters.”

– Ryan North, author of the Unbeatable Squirrel Girl comics and the non-fiction book How To Take Over The World.
