For historical fiction, check out
Shayne Parkinson's Promises to Keep quartet, of which the first,
Sentence of Marriage, is free, and
David Crookes' novels, of which
Redcoat is currently free.
Parkinson's books are focused on New Zealand and Crookes' on Australia. Both authors write exceedingly well. My wife and I, as well as our friends to whom we have recommended these authors and books, have found the books compelling and difficult to put down. We read Parkinson's books more than a year ago and still talk about them.
