A Thief in Time by Cidney Swanson

Halley's world is full of handouts and hand-me-downs. Even her apartment bedroom is shared, with her distant and self-centered mother. Halley has only a battered blue truck to call her own–until she meets Edmund, the second Earl of Shaftesbury. Edmund has a manor, employs dozens of servants, and has never been close to falling in love–until Halley crashes into his life during an accidental trip to 1598. Now a spiraling series of encounters with a dangerous time-traveling thief will bring their worlds together with heartbreaking ramifications.
