This is a strong debut fantasy novel and the start of a new series. Kinsella has a sparse writing style that will not satisfy anyone who's after a wordy Hardy or Tolkien-alike and allows the more foolish of us to make some assumptions about this new universe. However, the prose flowed well enough to get me over my initial, jaded assumptions and it is most definitely worth the time. This is not just a faux-medieval fantasy, but a stone-age people dealing with a much more advanced group of returning oppressors - who may be significantly beyond medieval if the series follows the potential "sword and planet" route rather than appearance of "sword and sorcery". Better still, the heroine turns out to be the shaman who rescues herself rather than the princess who waits in the castle.
