Due to some issues with LUE (Life, the Universe and Everything), I have recently escaped into the worlds of literary historical fantasy and been working my way through :

anything and everything by NZ writer, JULIET MARILLIER
(IMHO, she writes great characters and stories and many are set in ancient Ireland and Scotland).

However, other favourites where I have devoured most everything they have written are :

CHARLES DE LINT, Canadian fantasy writer
(esp love his Urban settings);
JOANNE HARRIS, English-French writer
(she of Chocolat fame);
DIANA GABALDON, American writer
(she of Outlander fame);
KATHLEEN O'NEAL GEAR & W. MICHAEL GEAR, American writers
(particularly like their 1st Americans prehistory novels);
SHARON KAY PENMAN, American writer
(loved her Welsh mediaeval history series);
PHIL RICKMAN, English supernatural/mystery writer
(he of the Merrily Watkins fame, set in the English-Welsh Border);
STEPHEN BOOTH, English mystery writer
(he of the Cooper & Fry Peak District detective novels.

A few years back, due to being caught up in (the younger!) Sean Bean's SHARPE DVDs, I also read and enjoyed the entire Sharpe series (mostly Napoleonic era) written by English writer, Bernard Cornwell!

Yeah, that's enough for now!
