Shadowplay is the second volume in the Shadowmarch quartet and carries the series past its halfway point. As with the first volume it's a competently-executed, traditional secondary world fantasy, but as a novel it's even slower-moving and more badly-paced than the first book.
The book is divided into several widely-separated narratives: Barrick and Ferras Vansen's adventures beyond the Shadowline, Briony on the run with a bunch of theatrical players, Olin as a captive in Hierosol, Chert the Funderling trying to help his amnesiac, adopted son and various characters in Southmarch living under the new regime. Unfortunately these narratives aren't really tied together well. They also vary wildly in quality and execution. The autarch's assault on Hierosol is tense and well-handled, but Briony on the road with the travelling players is dull. Even worse is Barrick's adventures beyond the Shadowline, where Williams aims for a kind of surreal mysticism and ends up with turgid boredom (though a few moments are genuinely unsettling). Chert, the most interesting character from the first book, is also hugely reduced in importance and gets little to do here.

The book's biggest problem is that whilst we have some big battles, some ominous scenes and some intriguing (if sometimes soap opera-ish) developments, the overall storyline doesn't develop very far. For only the second in a four-book series, it feels like Williams has far too many balls in play and is only able to move each of them forward a very small amount rather than the whole thing forward decisively (probably a reason why this trilogy expanded to four volumes).
The book is somewhat frustrating as Williams is still a good writer and some storylines and characters are well-handled, but overall the book's pace feels misjudged and there are no real surprises here.
Shadowplay (***) is a competently-executed fantasy novel, but the plot is slow to develop and there are too many storylines which feel extraneous or badly-handled to be really satisfying. The novel is available now in the UK and USA.
