When Laurel Martin is hired to rewrite the script for a new timeslip novel, she expects the historical advisor hired by the studio to be an elderly academic who won't interfere too much with her writing. But when she meets Professor Jason Harding, a young and unexpectedly handsome archaeologist who has some ideas of his own about the script, she realised the job isn't going to be as simple as she first thought.
As their work takes them from arguing over historical details in a cramped London office to discovering the hidden beauties of a Greek island, Laurel and Jason's relationship starts to echo the romance of their script. But with Laurel's actor ex-boyfriend making trouble at home, and constant issues with the volatile director, will Laurel and Jason ever be able to write the happy ending for their own story?
