Once Broken Faith

 Once Broken Faith by Seanan McGuire, 420 pages.

This is the tenth book in the October Daye series, and a more direct continuation than many others in the series (which means spoilers ahead). After Toby doing diplomacy went so "well" in A Red Rose Chain, Toby is commanded by the High King of the Westlands to attend the conclave that is being called to decide whether the cure for elf-shot should be distributed or suppressed. Being in a room full of royalty is never a good time for Toby, but it gets distinctly worst after the first murder. 

This book felt like a bit of a stopgap in the series. Which isn't to say it wasn't good, I thoroughly enjoyed the action and getting to see Toby digging into detective work again. But the overall tone is that this book is gearing up for something. It had more recap than most of the previous books of what had happened in the series to date, and also broadened the scale of the world considerably. I'm not sure what comes next, but I'm pretty sure things are about to scale up.
