• David Barnett in The Independent praises the novel, Invasion is not The Dice Man, and nor does it try or even want to be. However, it does share some themes of subversive humour and anarchic invention, In Rhinehart’s hands this is a terrific satire poking fun at politicians, the banks, the military and the gun-toting right, and is probably the best and funniest sci-fi satire you’ll read all year… at least until Donald Trump’s in the White House.'.^[1]
• James Lovegrove in the Financial Times writes 'Rhinehart’s 1971 novel The Dice Man is considered a counterculture classic, and the flip, zany humour of Invasion feels like a throwback to an era when widescale change seemed truly possible. The novel’s sneerily satirical tone can at times be off-putting, but amid all the hectoring and the curmudgeonly contrarianism there is a strong streak of moral indignation that few could fail to sympathise with.^[2]

Luke Rhinehart promised a sequel entitled The Hairy Balls and the End of Civilization, consisting 'of both hundreds of Protean definitions showing the real meaning of our most important words, and also Protean Proverbs, essays, Adages Revisited, and numerous witty and satirical illustrations, art works, and cartoons'^[3] told from the invaders perspective.^[4]
