Valentine's Day is one holiday that doesn't drive Amazon buyers, as no titles with a romantic theme or story made any big leaps leading up to the holiday. One exception is The Vow by Kim Carpenter and Krickitt Carpenter, ranked #16 on the bestseller list and #36 on the Kindle bestseller list (up 100% and 752%, respectively). Both rankings were sizable gains for the title, which was helped by the February 10 release of its film adaptation. The film exceeded expectations and grossed $41.7 million in its first weekend.
