Seventeen-year-old Keira Altman is the newest Legionnaire in the Legion of Pneumos, an ancient order tasked with wielding the power of pneumonancy to preserve order across worlds. Torn from her own reality and desperate to return home, Keira must navigate the treacherous politics of Loren while mastering a magic that feeds on the very chaos she's sworn to control.

But when the Regio of Loren is found on his deathbed and whispers of a rebel uprising send shockwaves through the kingdom, Keira's newfound power may be the only thing standing between order and anarchy. Joined by her grounder and best friend Danny, she embarks on a perilous journey to escort the naive young prince to safety and secure the line of succession.

As secrets unravel and betrayals cut deep, Keira finds herself at the heart of a conspiracy that threatens not only her life but the fate of the realm itself. With the lines between friend and foe blurring, she must decide whether to uphold her oath to the Legion or stand against the oppression of the people. In a world where chaos lurks just beneath the surface, one girl's choice could be the spark that ignites a revolution.
