This edition of the Book Club podcast is brought to you in association with serious readers who make a serious reading light.

It's got what they call daylight wavelength technology, which as far as I can tell, means it replicates the spectrum of daylight.

You can adjust its focus and brightness.

It's fantastically easy to position.

Use the offer code TBC to claim £100 of any HD light with free delivery and a 30-day

money-back guarantee. Go to www.seriousreaders.com forward slash Spectator.
