ABANDONED. A book series about a girl using a tomb to travel to medieval times

[Beck]

I read this book sometime around 2012-2013; it was a book series- with around five books in the series, I believe. The books were fairly long in length, and the cover was a dark blue, with gold engraving around it. I can't remember the title or author, or much of the plot unfortunately. what I do remember:

- the mc is a girl
- the girl went to a museum or something and visited a tomb- that's how she time traveled to the middle ages
- there's a scene in the first book when she's traveling on a wagon with a bard and some others
- there is a romantic subplot (i believe the love interest is the bard)
- as the story progresses through the books, the girl and some other characters arrive at an alter of an ancient god. the girl learns that she or one of her friends will have to sacrifice themselves so that she can go back to her time
- the love interest ends up sacrificing himself so that she can go back- and it works
- when she visits the tomb again, she finds out that the tomb is that of the love interest who died- but then he walks right out of it (it turns out *he* was the ancient god)
I hope that made some semblance of sense! it's been a really long time and i can't remember that many important details

The Crown of Dalemark, by Diana Wynne Jones?

Since his arrival in the North of Dalemark Mitt has become disillusioned. The North seems no more free than the Holand he fled, a fugitive accused of attempted murder. And now he is trapped by the order to kill someone he doesn’t know or else risk the lives of his friends. Forced once more to flee, Mitt is joined by Moril, the quietly powerful musician, and Maewen – out of her time, but mysteriously fated to play a part in their quest. For the evil powers of the mage Kankredin are re-assembling, and only the Adon’s gifts – the ring, sword and cup – can once more unite Dalemark.

Beck, can you tell us more about the girl (e.g., age, student or job, hometown)?

Is this series for teens or adults?
