A full-page review in the March 5, 2006
New York Times Book Review
"Marusek has the potential to make an indifferent audience care about science fiction again." Whatever the hell that means. Read the entire review. (Annoyingly, you have to register).

A starred review in Publisher's Weekly
"This extraordinary debut novel puts Marusek in the first rank of SF writers. . .Marusek's writing is ferociously smart, simultaneously horrific and funny, as he forces readers to stretch their imaginations and sympathies." Read the entire review.

Gary K. Wolfe in Locus

"David Marusek is one of the best-kept secrets of science fiction, a wild talent with a Gibson-grade imagination and marvelous prose, and a keen sense of human drama that makes it all go." Read the entire review.

Adrienne Martini in Bookslut
"It is visionary. It is goosebump inducing. It is challenging. It is just plain, stay-up-all-night-to-finish it good." Read the entire review.

Gavin J. Grant in the November 2005 BOOKPAGE
"Counting Heads is full of both invention and action.It is dense and thought-provoking,and its story pulls the reader along until the very last page.Let’s hope there’s more where this came from."

Sandra Boatwright in the Fairbanks Daily News-Miner
"Counting Heads is a great example of the best science fiction has to offer. The world of this book is complete and true to its own rules, down to the smallest details. . . "

David Moldawer at Dragon Page
". . .This is all preface to my labeling David Marusek an innovator, one of the elite few in hard SF. . . Best of all, Marusek is a terrific storyteller. This is an engaging and thought-provoking read. Highly recommended." Read the entire review.

John at SFSignal
"There are many elements of this apparent Utopia that are just plain cool. The first fifty pages had my head reeling with the implications of the nanotech." Read the entire review.
