Martina Cole: The Extras iPhone App is the definitive guide to bestselling author Martina Cole and is perfect for all her fans and those who are just discovering her fantastic writing.

We wanted to do something a little different when designing this iPhone App. As Martina's 16 hugely successful novels are set in London’s gangland we based the apps navigation around an interactive crime scene. Exploring the crime scene allows you to watch Martina talk about each novel, read the first chapter from each of the books, find out more about Martina in an exclusive extended bio and have instant access to buy the books you haven't read.
