Continuing a few months after Shadowblack, Charmcaster throws you straight back into the deep end. With Kellen meeting new Argosi and being warned he needs to leave Ferius behind, Nephenia appearing out of nowhere with a familiar in tow, Reichis being Reichis and the life of his friends at stake, Kellen adapts, learning new things, still being super whiny, but growing all the same. I really enjoyed this book and I'm looking forward to reading more from Sebastien De Castell. I like the style of his writing, although at times it can feel a little childish. The plot was so good, and leads right up to the next book in the series. As always Reichis is easily the best character in the book, but it's nice to see him interact with another familiar.
