Patrick Lee - Runner (Sam Dryden #1)

Sam Dryden, retired special forces, lives a quiet life in a small town on the coast of Southern California. While out on a run in the middle of the night, a young girl runs into him on the seaside boardwalk. Barefoot and terrified, she’s running from a group of heavily armed men with one clear goal—to kill the fleeing child. After Dryden helps her evade her pursuers, he learns that the eleven year old, for as long as she can remember, has been kept in a secret prison by forces within the government. But she doesn’t know much beyond her own name, Rachel. She only remembers the past two months of her life—and that she has a skill that makes her very dangerous to these men and the hidden men in charge
