Ranger Defender by Angi Morgan

She needed a miracle. She got a Texas Ranger.

Vivian Watts's mission to prove her brother's innocence has left her destitute and desperate. So when Texas Ranger Slate Thompson arrives with his knock–me–out blue eyes and belief in her case, she dares to hope again…until her apartment is burned to the ground. Slate offers safe refuge at his ranch, but when evidence suggests police corruption is at play, can he face down his own to protect her?
