The usual disclaimers apply. Books with hardcover domestic sales over 100K in hardcover or paperback were included in PW's list; publishers were asked to take returns into account, but these figures weren't often available at the time.
Here are the historical novels that made it on the list. See also my previous posts on this topic from 2012, 2011, 2010, 2009, 2008 and 2007.
Looking at hardcovers in 2013, one semi-historical novel made it into the top 15:
#5 - Nicholas Sparks, The Longest Ride, which traces an elderly couple's love story over decades, beginning in 1939. Did you realize Sparks had written a novel set in the past?
Topping the hardcover list was Dan Brown's Inferno (no surprise) with over 1 million copies, followed closely by Stephen King and John Grisham.
Other historical novels with 100K+ hardcover copies sold, in descending order of sales:
Jodi Picoult, The Storyteller (a perennial bestseller's first work of historical fiction; while mostly present-day, several threads are set in the past)
Elizabeth Gilbert, The Signature of All Things (read my review here)
Amy Tan, The Valley of Amazement
Fannie Flagg, The All-Girl Filling Station's Last Reunion
Kate Atkinson, Life After Life (which won the historical fiction category in the Goodreads Choice Awards)
Clive Cussler and Justin Scott, The Striker
Jhumpa Lahiri, The Lowland
Look at the wide range of settings: Nazi Germany, 1800s America, early 20th-century China, the 1940s South, 20th-century England, 1902 America, and 1960s India. None are set in the distant past, but nonetheless, readers can travel around the world through these historical novels.
This genre doesn't exactly thrive in mass market paperback format, so let's move on to the trade paperback list. Here we find Jess Walter's Beautiful Ruins (1960s), with 300K+ copies; Christina Baker Kline's unexpected bestseller Orphan Train, which had a nice PW profile last week; M.L. Stedman's The Light Between Oceans, a bestseller in hardcover; The Paris Wife, which continues well on the book club circuit; Ken Follett's mammoth The Winter of the World; The Storyteller again, in its trade pb re-release; Kate Morton's excellent The Secret Keeper... to name many in the 150,000+ copy range.
The top seller in trade paperback overall? F. Scott Fitzgerald's The Great Gatsby. And looking at e-books, the top historical fiction seller is The Storyteller again (400,000+ copies).
How many have you read? For me, just Signature of All Things and Winter of the World, but I have several others on the TBR.
