The first 100 pages were tough going. Perhaps it was that the cover and blurb suggested it would be about a convict ship experience and what happened after, but it was really about what happened before the convict ship and about trade and the textiles industry. So that was really misleading.
The writing was very descriptive, often overly so, which made getting through the first 100 pages of background setting quite laborious. After that, things picked up as the action started to really happen and the mystery was laid out.
I would have liked to have seen the connection between Rhia and her namesake the Welsh goddess Rhiannon explored and exploited a bit more. Rhia could have taken better advantage of her links to the Otherworld, but perhaps the author felt that going down this path would be too fantastical for the book she was writing, so it has a very minor role to play.
It pained me to read repeated comments about Rhia feeling as though her outspokenness had made her unattractive to men, yet saying she didn't care. The repetition though, certainly contradicted that. Other reviews, and even the blurb, have commented on it being a love story, but it is not a romantic love story.
The plot is complex and filled with many allegories, that of Rhiannon, textiles and the photogenic drawings, but the mystery is satisfying. In the desire to cram in so many characters, activities, locations, politics and intrigue, there were a few holes left unfilled and some convenient liberties taken, but it didn't detract from The Silver Threat being hard to put down.
