If you like legal thrillers, I recommend Rebecca Forster's books. I reviewed some of them in
On Books: Rebecca Forster — Legal Thrillers.
Also well worth reading are mysteries by these authors: Vicki Tyley (see
On Books: Murder Down Under) and L.J. Sellers (see
On Books: Detective Jackson Grows and Grows).
I don't think you can go wrong with any of these indie authors.
