Book Iron Flame Rebecca Yarros

In the first year, some of us lose our lives.
In the second year, we lose our humanity.

Many expected Violet Sorrengale to die during her first year at Basgiath Military College. However, the Threshing was only the first of a series of grueling trials designed to weed out the weak, the unworthy, and the losers.

Now the real training begins, and Violet is already worried about how she will cope. Not only is the second year grueling and incredibly brutal, but this year the riders must learn to withstand physical and moral pressure. But there is also a new vice-commandant who has made it his personal goal to prove to Violet how weak and frivolous she is, unless she betrays the man she loves.

And while Violet's body isn't as strong and resilient as the other cadets, she has a sharp mind and an iron will. And the leadership forgets the most important lesson you learn in Basgiat: dragon riders make their own rules. But the desire to survive this year won't be enough. After all, Violet knows a terrible secret that has been hidden in Navarre for centuries.
