Dan Brown's Inferno is, unsurprisingly, holding its #1 spot on both the print and e-book bestseller lists on Amazon, as of May 15. The hardcover has spent 120 days in the top 100; the e-book edition 96 days. The #2 bestseller in both print and e-book is The Great Gatsby. Another backlist classic, Dr. Seuss's Oh, the Places You'll Go!, is #5. The title gets an uptick every year around graduation time. Stephen King's sequel to The Shining, Doctor Sleep, is #88, over four months before its publication date, indicating a massive debut is in store.
