Turning sixteen was an exciting time for Grace, but it meant more to Brad than she ever expected. It was the night both of their virginities would be lost, in a culmination of years of friendship, never before pushed beyond a couple of stolen kisses. A night of lust turns to disaster for Brad when Grace recoils away from him, into the arms of another man. Grace marries that man, Lukas, and as time goes by she falls pregnant with his child, yet sadly loses the baby a day after she is born because baby Daisy's heart was weak. Brad, a musician, is trying to forget an abusive childhood at the hands of his father, whilst also wanting to let go of his love for Grace. He keeps his mother and his past guarded, but is one night drink spiked and coincidently nine months later Daisy is born. Brad has no memory of the night he was drugged and he can't help but wonder if Daisy was somehow his. A string of recent spikings come to light in the country Victorian town of Fletcher Valley. When Grace's best friend is murdered, the body count keeps growing. Secrets become poison, but it is also the poison that is the secret.
