Disappointment doesn’t even begin to cover my thoughts on this. Did it end the series well enough? Yes. Did it inspire me to read more of Schwab’s writing? No. Am I even more concerned that she is being compared to Diana Wynn Jones? YES.
A Gathering of Shadows and A Conjuring of Light aren’t so much book two and book three of the Shades of Magic trilogy as they are part one and part two of book two of the Shades of Magic duology. All three of the books in the “trilogy” take place in incredibly short amounts of time with a four month gap between one and two/three.
