There is a nice review of Five Wounds over at The Spectator Book Blog, by Isabel Sutton, which describes the book as an 'engrossing and original fantasy'. Here's an extract:
To my amazement, I began to lose my scepticism and turn the pages with a genuine care for the characters’ fates. I squirmed at the gruesome deaths and held my breath as the hero and heroine made their getaway; by the end I was greedy to know what happens, fully absorbed in the throes of the story. My progress was checked, however, when the ending arrived. There wasn’t one pat conclusion, but two. In a final act of literary guile, the book pushes you back to consider how – as well as what – you are reading.
