For fans of 'Throne of Glass' (Sarah J. Maas):

Grave Mercy

Common theme: assassins

Author: Robin LaFevers
Series: His Fair Assassin
Publisher: Boston: Houghton Mifflin, 2012.

Grave Mercy tells the story of how protagonist Ismae finds herself in the saving grace of a convent and out of the cruel fate of an arranged marriage. Only to discover she has been gifted by the God of Death, and must live a life full of danger and difficult choices if she is to stay at the convent.

I have chosen this title as it has in common with the Throne of Glass series the theme of assassins. In both series a young female protagonist is forced to use her gifts or talents as an assassin and perform difficult, grueling tasks to ensure her freedom. Both series’also include romance and have courts as part of their backdrop.
One of the biggest appeal elements for these series’ is the main character: a strong, gifted teenage girl who don’t let life just happen to them, they fight for the life they want no matter what it takes.
