In case you're looking for (research-y) summer reading stuff, you might want to check out
JSTOR, who have expanded their free reading scheme from six to one hundred articles per month, to support researchers during the COVID-19 crisis. This is very nice, and very generous!
You need to register with them for access (which is free), and then you can read up to 100 paywalled articles; there is also a number of open-access articles on their page.
Happy reading!
