Seeking SFF Dev Editor

Specifically, I’m looking for someone willing and able to take on book #3 in a Sci-Fantasy trilogy. I have not worked with a dev editor before, and I made it through the first two books but this one . . . Frankly, I’m stumped and need the help. I’m looking for someone experienced, but also willing to either do a quick read of books 1 and 2 to catch up or work from a detailed synopsis. I have a lot of story threads going, and I just can’t bear to mess this up.
