I think I did the right thing but I have ditched the publisher of my first two books after they licensed them, along with the rest of their back catalogue, to AI companies without asking authors first.
William Carey were great with my third book. Does anyone know any Christian publishers happy to taking on a training manual for church interpreters? Unlikely to be a best seller and won't generate many royalties as it'll be a multi-author thing but it's definitely needed.
