The Lie — C.L. Taylor

Jane Hughes has a great boyfriend, a job in an animal shelter, and a tiny cottage in rural Wales. She's happier than she's ever been...but her life is a lie. Jane Hughes does not really exist.

Five years earlier, Jane and her best friends set off on what was supposed to be the trip of a lifetime, but it rapidly descended into a nightmare that claimed the lives of two of her friends. Ever since, Jane has tried to put the past behind her and lead a normal life. But someone out there knows the truth about what happened-and they won't stop until they've destroyed Jane and everything she loves.
