Updated Thursday, 6th May 2021, 9:42 am An award-winning author and journalist from Marsworth is celebrating the release of her latest book with a launch event in Tring on Monday, May 10. Emma John's latest book, Self Contained, captures what it is to be single in your forties, from sharing a twin room with someone you've never met on a group holiday (because the couples have all the doubles with ensuite) to coming to the realisation that maybe your singleness isn't a temporary arrangement, that maybe you aren't pre-married at all, and in fact you are self-contained. The 42-year-old - who has released two successful books in the past - wrote the book during lockdown.
