Witness (Witness, Book 1) by Christine Kersey
BETTER WATCH YOUR BACK
This is the first book in a 2 book series.
College student Courtney Hartford's worries are confined to doing well in school and having an active social life. That is, until she witnesses a murder.
And then recognizes the murderer.
His warning not to tell, coupled with his threat against her life and the life of her mother, pushes her to make a difficult decision--tell the police the truth, or let the people who are threatening her control her life.
Witness is a clean and wholesome suspense novel.
