Into the Water surges upwards to claim another number one

Paula Hawkins' Into the Water (Black Swan) has claimed a second week at number one in the UK Official Top 50, selling 33,362 copies in paperback—a 37% bump in volume on the week before.

Gail Honeyman's Eleanor Oliphant is Completely Fine (Harper) spent a third week running in second place, but actually improved in volume in its 18th week of release, jumping 7% to 18,692 copies sold—and surpassing the 400,000-copies-sold mark. It is now the bestselling title of 2018 to date, defeating Tom Kerridge's Lose Weight for Good (Absolute).

Stephen King's The Outsider (Hodder & Stoughton) ousted Peter James' Dead If You Don't (Macmillan) from the top spot of the Original Fiction chart, for the veteran author's 19th number one in the category and his second (after Sleeping Beauties, co-written with son Owen) in under a year. Sleeping Beauties, now out in paperback, charted in 20th place.

Anthony Beevor's Arnhem (Viking) leapfrogged Jordan Peterson's 12 Rules for Life (Allen Lane) to swipe the Hardback Non-Fiction number one—the historian's 10th week in the pole, though only his third ever title to hit the category top spot. In 2009 D-Day spent eight weeks atop the chart that year and The Second World War added a ninth in 2012.

Adam Kay's This is Going to Hurt (Picador) scored the Paperback Non-Fiction number one for a sixth week running, selling 14,774 copies, and was the only non-fiction title in the overall top 10.

Liz Pichon's Biscuits, Bands and Very Big Plans (Scholastic) spent a third week running as the Children's number one, selling 7,593 copies—her 18th overall.

The print market was buoyant, posting a 3.5% boost in volume week on week to 2.86 million books sold, its highest since the first week of May. Against the same week in 2017, both volume and value jumped 3.8%, with average selling price dropping one penny to £8.21, its first year-on-year decline since the last week of March.
