Praise for How to Invent Everything:

Technically, we are all time travelers and we are all trapped. So, even if you happen to be scanning this blurb in what you perceive to be a 'normal' timeline, I heartily recommend you read this book cover to cover. -Zach Weinersmith, creator of Saturday Morning Breakfast Cereal and author of Soonish

A dazzling piece of work that's also genuinely hilarious. -Elan Mastai, author of All Our Wrong Todays

A witty pop science guide intended for those demanding times when one needs to create a civilization from scratch... wry humor keeps the discussion lighthearted. North's 'survival guide' is a fun, thoughtful, and thoroughly accessible reference for curious readers, students, and world-builders, as well as wayward time travelers. -Publishers Weekly (starred review)

Packed with cool, fun, and useful stuff... a friendly and thought-provoking reference, just the thing for the bright kid in the family, to say nothing of the neighborhood time traveler. -Kirkus Reviews

Praise for Ryan North and his books:

[Romeo and/or Juliet is] Shakespeare with even more sex, cryptography, time travel, and alternate endings than the original! Ryan North is the only writer I know who's smart enough and funny enough to pull this off. -Lev Grossman, author of the Magicians trilogy

[Romeo and/or Juliet is a] ridiculously fun book. . . . Ryan North is awesome. . . . It is as hilarious and funny and strange as you would imagine . . . so crazy, so much fun. . . . It's fantastic. -Book Riot

[The Unbeatable Squirrel Girl] was freaking hilarious . . . it's the closest thing the Marvel universe has to a classic screwball sitcom. -Nerdist Reference mixed with irreverence-that's what makes To Be or Not to Be so much fun. -Slate

Ryan North's The Best of Dinosaur Comics: 2003-2005 A.D. had me howling with laughter and passing the book around to whomever I could lay hands on to point out particularly good strips. Dinosaur Comics is an unlikely gem of a webcomic. -Cory Doctorow, Boing Boing

Machine of Death is a marvelous collection, riddled with intelligence, creative reach, and a frankness that makes the best use of the central gimmick. -Tasha Robinson, The Onion A.V. Club

This Is How You Die is a brilliantly addictive book that reads like a series of existential, death-obsessed Twilight Zone episodes. Very highly recommended. -Seth Grahame-Smith, author of Abraham Lincoln: Vampire Hunter
