The Pact (Sarah Roberts Book Seventeen) 
Sarah Roberts has lost her ability to hear her sister’s messages. All forms of communication with Vivian are gone. Unless Sarah fulfills a pact with Vivian, one she knows nothing about, their ties will remain severed forever. 
In a time capsule Vivian prepared almost twenty-five years ago when she was still alive, prophecies and documents await Sarah. Several of the documents are addressed to people Vivian thought Sarah might know in the future. When Sarah’s father mails these documents, Sarah’s world is flipped upside-down. Instead of Sarah hearing her sister and performing tasks, Sarah’s friends are the ones hearing Vivian’s words through the letters she wrote to them years ago. 
Back then, Vivian hadn’t been clear on what each person should do to save Sarah’s life. Since the near future affects Sarah personally, Vivian cannot intervene and communicate with her directly. 
The future becomes the enemy and the only way to stop it is to cease moving forward, to die. Sarah fights to stay alive without any spiritual guidance, something she has never done before, which becomes her undoing when she walks into a trap she cannot walk away from, and no one is there to save her.
