"Franzen reveals moments of absolute genius. The cathartic power of tennis; the debilitating effects of jealousy; the fickle, fleeting nature of fame; and the slow death of youthful idealism are all beautifully captured."
— Library Journal
"Franzen has created a spectacularly engrossing and provocative twenty-first-century improvisation on Charles Dickens' masterpiece, Great Expectations . . . Purity will be one of the most talked about books of the season."
"A twisty but controlled epic that merges large and small concerns: loose nukes and absent parents, government surveillance and bad sex, gory murder and fine art . . . [Franzen is] admirably determined to think big and write well about our darkest emotional corners. [Purity is] an expansive, brainy, yet inviting novel that leaves few foibles unexplored."
— Kirkus Reviews
"As with all of Franzen's fiction, there is much to admire in Purity, not least what reviewer David Gates once termed 'microfelicities,' the expertly calibrated turns of phrase and pleasingly digressive cultural references and riffs around every corner. Like his last two novels, Purity bends time, easing in and out of characters' pasts and presents until, before you know it, the disparate pieces of a life suddenly fit"
