My books are available on Amazon, Barnes and Noble, Kobo, Smashwords, Itunes, Livraria Cultura, Indigo, and various other international stores. Please note that not every title can be found everywhere because various retailers have individual policies about what can and cannot be posted.
If you want to be notified when a new title of mine becomes available on Itunes, Books2Read has created a place where you can do this. Just follow the link to Books2Read and enter your name and email. Books2Read also has links to my books that lead to a variety of international market places where you can find my books, not all of which are listed above.
