Lose Her If You Love Her (Spencer Reid/Criminal Minds/AU)

Poppy San Gareno, a 23 year old, smart but wild child. She enjoys using her analytic skills to prank people around her. After being fired for most likely the fourth time due to her extreme personality, an old family friend offers her a job at BAU - the Behaviour Analysis Unit - for the FBI. That friend is Special Agent Aaron Hotchner, Hotchy as Poppy likes to call him.
At BAU, Poppy meets Dr Spencer Reid and immediately feels drawn to him. Maybe it's his extensive collection of smart dress shirts and ties. Maybe it's his eidetic memory and capability to read 20,000 words per second. Maybe it's his socially awkwardness. Either way, Poppy doesn't know. But she doesn't care. She will always get what she wants, and what she wants is Spencer.

There's only one problem.

Poppy has a secret. A big secret. And she doesn't plan on telling anybody. Including Spencer. So what happens, when she is forced to reveal a secret that could destroy everything she has so carefully built?
