Vivian Lahey moved to the glittering capital city of Reinfell to escape from her past. But now it has followed her there. Her work as a thief has always been dangerous. When a friend from her previous life appears in an alleyway and pulls her into a network of espionage and politics inside the palace, her life reaches new levels of peril and urgency. Together with a team including a gentle prince, a cunning lady of the city, and a shadow-friend from her past, she infiltrates the court and works to uncover a plot that may endanger the whole city. As she uses abilities she has long kept hidden and pries deeper and deeper into the court to discover the danger hovering over her beloved city, she exposes secrets about her past and the city that may destroy the very life she has built.

Kaida wakes up not knowing who she is, or where, or whose voice that is, telling her it's time to go. All she knows is that there are gunshots and screaming wherever she is. The Elementals tells the story of Kaida Niremaan, the Queen of the Southern Nation. She has lost her memory, she doesn't even remember her true love. She learns that she is an Elemental, along with four others. She has the Fire Element, but she doesn't know how to use it. She finds out that there are a certain group of people, who are called the Rebels, and worst of all, they originated in her kingdom. They want to capture all of the Elementals because they think that the Elementals should be in cages, instead of in a place of power. She has to cope with all of this forgotten knowledge coming to her, her powers, her kingdom, the Rebels, but most of all, her forgotten love.
