"[An] instant classic. . . . One of the most hilarious and emotionally riveting love stories you’ll ever encounter." —People

“Big, absorbing, smart, fantastically readable." —Nick Hornby, from his blog
 
"[Nicholls] has a gift for zeitgeist description and emotional empathy that's wholly his own. . . . [A] light but surprisingly deep romance so thoroughly satisfying." —Entertainment Weekly

“Nicholls offers sharp dialogue and wry insight that sounds like Nick Hornby at his best.” —The Daily Beast (A Best Book of the Summer)

“[One Day] will leave you hungrily eating up the words. At times, you will experience ‘can't breathe’ laughter, then ‘publicly embarrassing’ sobs. Whatever emotion, all will feel uncontrollable; precisely like the lives of the characters you so badly want to see end up together.” – Seattle Post Intelligencer

"Fluid, expertly paced, highly observed, and at times, both funny and moving." —Boston Globe

"Those of us susceptible to nostalgic reveries of youthful heartache and self-invention (which is to say, all of us) longed to get our hands on Nicholls’s new novel. . . . And if you do, you may want to take care where you lay this book down. You may not be the only one who wants in on the answers." —New York Times Book Review

"Who doesn’t relish a love story with the right amount of heart-melting romance, disappointment, regret, and huge doses of disenchantment about growing up and growing old between quarreling meant-to-be lovers?" —Elle, Top 10 Summer Books for 2010

“A great, funny, and heart-breaking read.” —The Early Show [CBS]

"Funny, sweet and completely engrossing . . . The friendship at the heart of this novel is best expressed within the pitch-perfect dialogue/banter between the two." —Very Short List

“A wonderful, wonderful book: wise, funny, perceptive, compassionate and often unbearably sad . . . the best British social novel since Jonathan Coe’s What a Carve Up!. . . . Nicholls’s witty prose has a transparency that brings Nick Hornby to mind: it melts as you read it so that you don’t notice all the hard work that it’s doing.” —The Times (London)
 
“Just as Nicholls has made full use of his central concept, so he has drawn on all his comic and literary gifts to produce a novel that is not only roaringly funny but also memorable, moving and, in its own unassuming, unpretentious way, rather profound.” —The Guardian (London)
