Prologue

Trust.

A five-letter word. Easy to spell, easy to remember, but difficult to do.

It's hard to trust people. Your colleagues, friends, and sometimes even family....

With a rough past and some trust issues, 27-year-old Lina Yang joins the Behavioral Analysis Unit at the FBI, where she must learn how to trust her colleagues. After all, she has a dangerous job and there may be cases where she needs them to have her back.

But when she meets Spencer Reid, a 25-year-old genius, her whole world changes. She starts to let down the walls she built to protect herself, and allows someone special into her heart.
