We'll talk about a different theme each week....and this week we are taking a look at history books.

Today's Chris Mason is joined by special guest Greg Jenner, a historian and historical consultant to CBBC show Horrible Histories, and is the author of four books, including ‘You Are History: From the Alarm Clock to the Toilet, the Amazing History of the Things You Use Every Day’.

We will be joined every week of the school summer holidays by the author Frank Cottrell Boyce and librarian Jennifer Horan.

Join us next week for books about nature and climate.

You can find all of our recommendations on our Twitter @bbcR4Today and Instagram and Threads - both @bbctodayprogramme.
