Throne of Glass is the first book in an epic series. Celaena Sardothien is an extremely skilled assassin who has to compete in a dangerous competition against other assassins to win her freedom. But when her competition starts turning up dead, she begins to realize there's something dark and wild at play. And that's only book one!
Let us tell you, this series will take you on a wild, magical, breathtaking, heartbreaking ride. One thing Sarah J. Maas does extremely well is creating strong female protagonists that evolve and change over the course of the series. Plus the world-building is exquisite. Six books in the series are currently released; book seven is awaiting a release date.
