This book not only covers the usual wall section, but also the rest of the area. Maryport gets a mention. And so does Ravenglass! It's on page 164, under the section covering Civilians and the Wall, and concerns the excavation of the vicus undertaken in 2013-2014. The author has obviously read the publication (large file which may take several minutes to download) which was written by Kurt Hunter-Mann and produced by ArcHeritage.
