Re:Generations is the fourth instalment in the Virgin Decalogs series — a series of books which each contain ten tales wrapping around a common theme. This was the first of two Decalog collections published after the expiry of Virgin Publishing Ltd's licence to publish Doctor Who fiction; however, Virgin still retained the right to publish novels based upon characters created in the Virgin New Adventures series. Re:Generations consists of ten stories following the lives of the family of Roz Forrester, onetime companion of the Seventh Doctor.
