Eclipse was published with an initial run of 1 million copies. The book replaced J.K. Rowling's Harry Potter and the Deathly Hallows on the top of bestseller lists around the globe, including the New York Times', even though Deathly Hallows had been released only two and a half weeks earlier. Eclipse peaked at #1 on USA Today's top 150 best sellers list and has gone on to spend over 100 weeks on the list, and was later ranked #45 on their list of "Bestselling Books of Last 15 Years" in October 2008.
Anne Rouyer of School Library Journal said that, "Meyer knows what her fans want: thrills, chills, and a lot of romance, and she delivers on all counts." Selby Gibson-Boyce of Tulsa World wrote, "I read without stopping until I finished. Meyer's book would not detach itself from my hand. Exactly the same thing happened with Twilight and New Moon." Publishers Weekly wrote, "The legions of readers who are hooked on the romantic struggles of Bella and the vampire Edward will ecstatically devour this third installment of the story", while noting that, "it's unlikely to win over any newcomers."
