"Fast and deep…I like the galaxy this author's playing in, the characters he limns, the situations he's playing with, and I'm glad there's at least one more volume on the way." — San Diego Union-Tribune on The Ghost Brigades
 
"In Heinleinesque fashion, the book is loaded with scenes of comradeship, isolation, ruthlessness and the protocols, which govern the lives of active-duty soldiers. But this is where Scalzi, famous for his blog ‘The Whatever,’ surpasses Heinlein. Scalzi weaves in subtle discussions of humanity's growing fear of aging and our simultaneous attraction and repulsion to the Frankenstein-like creatures we are able to create." — San Antonio Express-News on The Ghost Brigades
 
"Scalzi is a natural heir to Heinlein, and his second book in this series is a good old-fashioned space opera, which takes time to question the nature of free will." — St. Louis Press-Dispatch on The Ghost Brigades
 
"Astonishingly proficient." — Publishers Weekly (starred review) on Old Man’s War

"Smartly conceived and thoroughly entertaining, Old Man's War is a splendid novel." — Cleveland Plain-Dealer
