Jumia Books Crown of Midnight (Throne of Glass, 2) by Sarah J. Maas

“A line that should never be crossed is about to be breached. It puts this entire castle in jeopardy—and the life of your friend.” From the throne of glass rules a king with a fist of iron and a soul as black as pitch. Assassin Celaena Sardothien won a brutal contest to become his Champion. Yet Celaena is far from loyal to the crown. She hides her secret vigilantly; she knows that the man she serves is bent on evil. Keeping up the deadly charade becomes increasingly difficult when Celaena realizes she is not the only one seeking justice.
