For light reading, I recommend:

Things My Girlfriend and I Have Argued About, by Mil Millington: https://www.amazon.co.uk/Things-Girlfriend-Have-Argued-About...

and form the acting world (but these are totally great to read on their own) I can recommend:

Awkward Conversations With Animals I've Fucked by Rob Hayes: https://www.amazon.co.uk/Awkward-Conversations-Animals-Fucke...

and The Truth, by Florian Zeller: https://www.amazon.co.uk/Truth-Florian-Zeller-ebook/dp/B01CV... (side splitting performance in London two years ago)

and if you're into it: http://www.hpmor.com/ . A bit fringe, but worth a shot if you've read the original books.

All of these are lighthearted and fun.
