The summary of Onyx Strom by Rebecca Yarros.pdf is below
Violet Sporangial is aware that there is no more time for classes at Basquiat War College after almost eighteen months. There is no more time for doubt. It’s hard to know who to trust because the battle has really started and enemies are encroaching from both inside and outside their ranks.
In order to support Navarre, Violet must now travel outside of the failing Arietian wards and look for allies in strange places. She will put all of her strength, cunning, and luck to the test on the journey, but she will stop at nothing to protect her home, her family, her dragons, and him.
It could ruin everything, even if it means keeping a secret this big. An army is required. They require power. They require magic. And they require just one item.
