SHOREFALL
This series is rapidly becoming one of my favorites. You can read my review of FOUNDRYSIDE, the first in the series.
The character work(their likability, complexity of thought and variety of personalities as well as chemistry) and prose is excellent. The world building/magic is excellent and wonderfully tangible/ intractable. The plotting is delicious (the way it progresses and changes and graduates, the way it becomes increasingly thorny and difficult to resolve, the narrative twists/turns) on so many levels, with the antagonists being spectacularly threatening, intelligent, and visual/ominous. Just wonderful.
On a side note, there is so much good writing on display in this book (good writing on a technical level) that it would be a good book to study for aspiring writers of an intermediary level (specifically those of the sci-fi/fantasy genres) concerning plot.
With over 21,000 ratings SHOREFALL has a solid 4 star rating on Goodreads.
