Hannah Kaner is definitely one to watch! Godkiller is a cozy fantasy, with just the right amount of action, found family & romance. As Kaner is a Northern author, I instinctively read Kissen's dialogue in a northern accent, so to see her using some Geordie dialect was so great! A lovely little nod to where she's from. 
The character development was really lovely to see, especially those found family feels of a band of misfits and strangers coming together as friends, only to be torn apart at the end! Big cliff hanger that's left me desperate to read Sunbringer. It's classic, well know format, a great read from start to finish. The world building is really well done, I think Kaner actually did really well to reign in with the world building as  I think it could have been huge, and probably overwhelming. I'm really looking forward to seeing where the gang takes us next.
I can't finish this review without the mention of Skedi, the delightful, albeit mischievous little Godling. I really hope we see more of his story in Sunbringer.
