The most popular books of the week is our regular feature that lists the 20 most popular books on Books in the Media during the past week.
We measure popularity by tracking the number of views of each book via Google Analytics. The current period is Monday to Sunday (30 December 2019 - 5 January 2020) inclusive.
Overall traffic to our books section rose significantly - by 14.9% - compared with the same period the previous week (or year, or even decade). The top slot was taken by our old favourite, Robert Harris's futureshock thriller The Second Sleep, which has been a fixture on these charts for the past 13 weeks.
The 'twixtmas' lull in new releases means that the highest new entry of the week is down in seventh place, where J M Coetzee's timely The Death of Jesus appears with a 122% rise in views over the previous week.
The second highest new entry this week is Kiley Reid's Such a Fun Age - a broadly acclaimed debut which drew comparisons with Sally Rooney - which entered the chart in the number 9 slot with a 900.0% boost in popularity over the previous week.
The chart shows this week's position - with last week's in brackets - followed by the week-on-week change in popularity, as measured by page views.
