I enjoyed this book. It was a little difficult to get into, but once I became invested in the lives of the characters, the story flowed at a good pace. I'm not sure how to classify this book. It's part coming of age story, part Arthurian legend retelling, part urban fantasy, part portal fantasy. It's pretty ambitious. I feel like Speakman has enough skill to pull it off, but just enough. I've read a little of his later short fiction and felt it worked better than this book did.
To be honest, there are some issues, some redundancy, a bit of klunky or awkward dialogue, etc., that I think would put off some more experienced readers who have read more experienced authors.
I'd recommend this book to readers just getting into fantasy or those who know how to avoid nitpicking and just enjoy a good story. Because when all is said and done, the story is quite good and even fairly original. Another bonus is that no loose ends were left to dangle. It felt complete and didn't leave me wondering what happened to such and such character or such and such plot point. I look forward to reading what follows in the series.
