Kryptonite by Anna Widzisz

“Here in the darkness you know me, and I know you. So we won’t ever get lost.”
Four years wasn’t long.
Though for some it was.
Month after month, Elio tried to get his life together. Because he didn’t have Savannah anymore. She was gone, and he didn’t know where she went, or if she would be back.
The pain stayed. Anger boiled.
When he stopped hoping to see her, Savannah was back in his life. Forced to face the underworld she wanted to leave behind forever. The one she chose to escape from.
Her life was in danger, and Elio seemed like the only person who could help her.
But she kept a secret… a few, in fact. Something that could make or break them again. The problem was – she wanted to stay an outsider.
Elio was her kryptonite. She loved him, but she couldn’t have him. Not under those circumstances. Not in this world.
