Garnet's story came out after the first two books in the Lone City Trilogy, and follows in the trend for teenage fiction, of giving us a novella from a different character's point of view. This follows the same time period as the first book in the series 'The Jewel' so it doesn't particularly move the story forward any, but it does give us a lot more insight into Garnet, son of the House of the Lake.
We don't see much of Violet in the book, which I'll admit suits me as, as is often the case, I find the main character the least interesting.
Turns out that Garnet's motives were more self-centred than I had originally assumed, but for all that I found that I liked him more for it. Garnet is one of the more interesting characters in the series anyway, so finding out that he wasn't just an idealistic teen was quite a nice change. It also turns out that almost every assumption I'd made about why he did things was wrong, which I like, it's nice to be wrong and not always know what's going to happen.
This novella also gives us a bit more information about Garnet's relationship with his wife to be, Coral, who I had pretty much forgotten about, so that was interesting as well. I think I'd like to head the second and third books for Garnet's point of view as well, he and Raven are (for me) the most interesting characters and anything from their Point of View gives a very different look at things.
This novella is more coherent than the one based around Raven, because of what that was about it was very easy for that to become disjointed as she did, for a time, become quite an unreliable narrator, you don't have that problem with Garnet.
I am really enjoying this series and am currently half way through the final book in the series, so chances are I'll be talking about that one in the next few weeks as well.
