I regret to say that "The Isles of Glory" trilogy (The Aware, Gilfeather and The Tainted)
is at the moment not available as eBooks.
Havenstar is no longer available on Amazon as an eBook, but can be bought through many other eBook outlets.
I am working at the moment to find another eBook publisher for them all, on a more permanent basis.
Why don't I do it myself?
Basically because I am a writer, not a publisher, and I no longer have the inclination or the time to mess around with the production issues, financial issues, etc.
