Hunting the Witness by Kate Angelo

Attacked in the mountains — with no memory of why…

She’s the only witness to see the face of a killer, but a deadly attack leaves Belinda Lewis unable to remember even her own name. She’ll have to rely on her rescuer, FBI special agent Jonah Phillips, to survive repeated attempts on her life — but she doesn’t know he’s in hiding because his description matches the killer’s. Can they unmask the true criminal to clear Jonah’s name and save both of their lives?
