Finished reading Imperial Spy this week, and generally enjoyed it.
It's obviously aimed at the Young Adult market in how it's written, but it's sharp and well-paced, and I had no problems at all getting into it.
I had a couple of niggles - but this is common with every book I read
- but there was nothing really wrong with the story itself.
I especially liked the extra details that helped make it more real, such as regarding the use of poisons and traps, and I found the handling of death profoundly handled (especially regarding the cells and young guard).
Overall, I'm sure the younger readers will especially enjoy reading Imperial Spy.
