The Missing Variable | Criminal Minds

Five years ago, Dr. Spencer Reid lost the love of his life.
Since then, his world has become painfully simple: work, his daughter Daisy, and the people he'd do anything to protect.
When a new profiler joins the BAU, getting close to Spencer Reid is the last thing on her mind. He's brilliant, guarded, and carrying the kind of grief that never truly leaves.
She doesn't expect a curious little girl who lives three houses down to become a part of her daily life.
She doesn't expect the BAU to feel like home.
And she certainly doesn't expect to become the one variable Spencer never accounted for.
But some equations are never as complete as they seem.

Or, five years after losing everything, Spencer Reid learns that moving forward doesn't mean leaving the past behind.
