I have self-published my first collection of dark short stories/flash fiction as both paperback and ebook; it's called Bottles and Pots, and is on amazon in the UK and in the USA. It's been well received, and an issue of Freelance Market News gave it a quarter-page feature. Included are pieces that have been shortlisted, commended or placed in competitions, or that appear in anthologies elsewhere.
There are two self-published Millie the Detective series of short novels for children 8-11. The first is Millie the Detective and the Diamond Ring and the second, Millie the Detective in The Thief Unmasked. Both are available in paperback and for Kindle. There have been book-signings and talks featuring Millie, her brother Dave, his best mate Joe - and Boris the Dog! Writers' News gave them a short piece in their Subscriber Spotlight.
