About Author
I'm in my late forties, my interests are varied but since menopause hit a few years ago, I find myself becoming a "grumpy old woman" all too frequently - where has my infinite patience gone!?! Lol!
I bought a Kindle in the summer of 2013 and haven't stopped reading since. If you want to know more about me, check out my blog - www.florasmusings.com
