The Guardian's Angel

When nobody knows what to do with a troubled, damaged kid, it’s time to call Elizabeth Driscoll. A wary, vulnerable, unusually intuitive young woman, Libby has a knack for helping children that others have given up on. Certainly nobody knows what to do with Tommy Madden, least of all his fiercely devoted guardian, Seattle Police Detective J.D. McCammon. McCammon believes the autistic little boy witnessed a double murder: his mother and his father, the city’s District Attorney. J.D. is determined to help and protect Tommy at all costs, and somehow, find a way to communicate with him. When Tommy’s life is threatened by the corrupt organization that killed his parents, J.D. and Libby take him on a desperate and dangerous flight to safety. They must place their trust in one another to escape a relentless evil that threatens not only their lives, but that of the child they’ve both come to love. On the run, Libby and J.D. are tested to the limits of their courage and resolve. They discover an intimate and mystifying bond that will either drive them apart, or become their greatest source of strength and passion.

I love this book actually wish that they would've made it in two parts and made it even a little longer
