Twin Flames - Olivia Abtahi

On estranged twins Leila and Bianca's eighteenth birthday, Leila suddenly gains a djinn's superpowers, and the twins realize that their town can only survive the djinns' secret plans if they learn to work together as sisters. An action-packed YA fantasy!
Twins Bianca and Leila could not be more different from each other. Being both Argentinian and Iranian in a small town has always been hard, but with Leila shunning her heritage and Bianca embracing it, the two walk very different paths. They run in different circles of friends, and barely talk anymore. Leila's a homebody who loves to craft and plans on marrying her high school sweetheart. Bianca's more anti-establishment and plans to get out of Dodge as soon as humanly possible.
But on their eighteenth birthday, the neighbor's barn mysteriously burns down. When Leila encounters a monster--a djinn--arising from the fire, suddenly she gains strange powers and can no longer touch iron.
What do these djinn want with Leila--or other people in town, for that matter? Can the twins learn to rely on each other--and their cultures--to banish them? It'll take a sisterly reconciliation for the girls to find out and to save their hometown in this New Visions Award-winning fantasy adventure.
