Jethro Cane's life has changed a lot in three years. Ever since meeting the Doctor, he has promised to see more of the world, become more of a person. So he joined the Time Agency. One day, he realises they are taking his memories, and soon finds himself on the run, and begins his own journey throughout time as he realises that everybody who has known the Time Lord is in grave danger. Working with one-time companions Sally Sparrow and Timothy Latimer, he frantically tries to gather all of the Doctor's old friends so they can find him before it's too late, and the universe is in danger once more. Whoever is hunting the others is smart, and has all of the Time Agents willing to do whatever it takes to find the Doctor... and kill him once and for all.
