The Silver Chain is the first book in the Unbreakable trilogy by Primula Bond. It's an okay read. I had several issues with this book. The most notable is the excessive inner dialog. The Silver Chain is told solely from the point of view of the heroine, Serena. It is long winded and rambling. The plot moves at a snail's pace because you have to slog through pages and pages of inner dialog. So much time is spent on Serena's inner musings that it fails to give depth to the plot, the romance, and to the hero, Gustav. 
 Additionally, I didn't find it sexy or erotic. I'm not a prude in any way and have read and enjoyed more erotic and kinky books but the erotica in this book felt forced, awkward and at times ridiculous. The flow is off as well, it jumps from one scene to the next in a jarring fashion. The overall plot is interesting but there isn't much progression and it ends in a cliffhanger. I'm sorry to say that I have absolutely no interest in reading the next book.
