If Too Like The Lightning frustrated you, steel yourself and read this anyway. The payoff on your investment will be huge. TLTL was often a slog, but this is not that - complex, yes, but also moves at an amazing pace, with the most satisfying ending of a second book in a trilogy(?) that I can remember. Well worth the read.

(I do recommend rereading TLTL before reading this - there are a lot of details in the first book that get tied in to the second book, so having it fresh in your head will enrich the reading experience.)
