Just finished the Blackthorn & Grim series by Juliette Marillier, it's definitely a 'pick' from me. The first book in the series 'Dreamers Pool' was gripping from the start. The characters were gritty and engaging, you feel involved in their story and you want to follow it through to the end.
My only gripe is that the endings of each book (especially the last) felt rushed and 'convenient'. But that doesn't take away from the enjoyment.
