Buying Time 

A bold new time-warping direction for a leading light in science fiction. In January 2017, something very strange happens to screenwriter Ed Richie. He wakes up one morning to find that he has been shunted back in time nine months and is now inhabiting the body of his younger self… Worse is to come: the following day he jumps three years, to 2013, with all his memories of the intervening years intact. What is happening to him? Is he going mad? And where will his involuntary time-travel end? Meanwhile, in 2030, journalist Ella Croft is investigating the life of screenwriter and celebrated novelist Ed Richie, who mysteriously vanished in 2025. She interviews friends, acquaintances, and old lovers — and what she discovers will change not only Ed Richie’s life, but her own… Buying Time is a time-travel novel like no other. No man is rich enough to buy back his past — unless that man is Ed Richie… From multiple award winning author Eric Brown.
