The story is gripping, the characters are terrific and the writing is clever and funny. As intelligent as it is enjoyable
It's a proper novel. By which I mean, not that it has pages you actually turn - that is optional with novels nowadays - but pages that you actually want to turn, which is getting rarer and rarer.... Charming, gently comedic, sweetly nerdy and enthusiastic about media both old and new
Rollicking... an ode to the beauty of dead-tree books
New York Times
Delightful... Smart, hip and witty
The pages swell with Mr Sloan's nerdy affection and youthful enthusiasm for both tangible books and new media... A clever and whimsical tale with a big heart
Both comforting and thrillingly odd... Shelve it alongside Where'd You Go Bernadette and your hipster cookbooks, and savour
Through narrative and email correspondence, Sloan captures contemporary work environments, current reality, and future trends . . . [Sourdough] offers much to savor.
[Sourdough] plunges through so much terrain: microbial nations, assimilation and tradition, embodied consciousness and the crisis of the tech industry, all without losing the light, sweet, ironic Sloanian voice familiar from Mr. Penumbra's, a plot that makes the book a page-turner and a laugh-out-louder, with sweetness and romance and tartness and irony in perfect balance. What a great book, seriously.Cory Doctorow
A wild, geeky, flour-dusted ride through the oddball food and techie communities of San Francisco . . . A winning story that--like its namesake bread--carries a satisfying tang.
Genius-level observant, wonderfully written and brilliant.
