Sarah J. Maas
In this second book of the Throne of Glass series, Celaena must carry out her duties as King's Champion, assassinating enemies of the Crown. As she becomes involved in searching out conspirators, she suffers heartbreak, discovers more dark magic, and finds her loyalties tested.
The first three-quarters of Crown of Midnight move slowly, especially dragging during Celaena's period of grief. I nearly gave up at several points, but I am interested enough in the overall story to stick with it.
The last quarter was action packed, with a shocking cliff hanger that nearly made up for the occasional tedium of the rest. Despite it not being a gripping novel, I plan to continue the series, as I have enjoyed Maas' other series (Crown of Thorns and Roses) and expect that, as she matured as a writer, the Throne of Glass series improved.
