Ranger Protection by Lynn Shannon

When Dr. Tara Sims is robbed, she fights back to protect her daughter and nearly pays with her life. She’s rescued by Texas Ranger Grady West. Her childhood friend is now a handsome lawman, but Tara refuses to acknowledge the chemistry sparking between them. With a little girl to raise and a growing medical practice, she has no room in her life for romance.
Grady suspects the vicious assault wasn’t a random act. What he can’t figure out is why anyone would attack the single mother. He vows to protect Tara and her little girl while keeping his growing feelings for them out of the equation. Getting romantically involved with his sister’s best friend is more hazardous than hunting criminals.
As the threats escalate and evidence links the robbery to a homicide, Tara and Grady realize nothing is quite as it seems. Untangling a web of secrets makes them the target of a madman, and it’s only a matter of time before the killer strikes again…
