Dangerous Lies - Becca Fitzpatrick

A teen is forced to make a fresh start after witnessing a violent crime--but love and danger find her anyway in this "swoonworthy romance" (Kirkus Reviews) from Becca Fitzpatrick, the New York Times bestselling author of the Hush, Hush saga.
Stella Gordon's life is a lie.
She does not belong in Thunder Basin, Nebraska. As the star witness in a murder trial against a drug dealer, Stella is now in the Witness Protection Program. The small town locals can never know who she really is. Not even Chet Falconer, the one boy who makes her want to reveal her true self. She knows that telling the truth will only bring violence to this safe haven.
Despite how hard Stella tries to stay under the radar, danger is fast approaching. Criminals have a way of getting rid of witnesses, and Stella may have made the one mistake that could lead the cold-blooded men hunting for her right to her doorstep.
