Harley 》Klaus Mikaelson

"He was the rock in her chaos that the rest of the world splashed off of."

Harley Quinn is a psychopath, on that everyone could agree. But she's also a psychopath that would do anything and everything for the people she loves. With a twin sister that always finds herself in trouble, Harley was always needed. So it was obvious that she would come bolting to New Orleans when she learned that her sister is practically a hostage to a band of witches. But what Harley didn't expect was for Niklaus Mikaelson, the father of her niece/nephew to catch her eye. He was insufferable, egotistical, psychopathic and a monster and Harley loved every part of it. A hybrid with a temper was one thing but throw in a heretic with anger issues and a fierce need to protect her sister? Absolute chaos.

Or

In which Harley Quinn stumbles into the impending doom that is the Mikaelson family.
