I had the honour of interviewing RJ Barker for SFFWorld a couple of weeks ago. He’s a fab person and his energy comes through in his work.
Subjectively Age of Assassins fell short for me, in one majorly minor way having lived all my life in the shadow of someone who is disabled. Much in the same way FTL gets in the way of other peoples read, my little grumble would cast shade over what is a fast fun read for the majority.
It does address the call for diverse books, perhaps not in the way some intend. Reading between the lines I suspect more will be addressed as the series progresses. Patience, as the say is a virtue and I look forward to seeing where RJ takes the reader next.
