Another short story in the Seventeen series that you can now get for free if you subscribe to the author's newsletter.
In this (very) short story Lucas wants to train in Japan.
I wished the story would have been a bit longer, because it really felt too short to add anything substantial to the overall storyline. Also, I'd like to read a bit more about this Japanese period. That doesn't mean it was not an interesting read, but it felt too short for me. But as it only takes about half an hour to read, I'd recommend it anyway!
Dancing Blades is a short story prequel to the Seventeen series. There are more short stories like First Death and The Meeting, as well as four full length novels called Soul Meaning, King's Crusade, Greene's Calling and Ashstorm.
