What's the Name of That Book??? discussion

Hi,
Hopefully someone has read this book before.
Just like I have it in the topic heading.
I think it started with them fighting in Afghanistan and were transported through time when they hide in a cave.
The characters were marines or sas, and they were trying to get back to their own time, and they have to live with Vikings while trying to find their way back.
I got it through Amazon I believe on my kindle. But for some reason it's not showing up in my history.

Thank you in advance
:D

Possibly A Long Time Until Now by Michael Z. Williamson

Thank you, but no that was not the one.

It was definitely strictly Vikings. They didn't come across anything else.

So frustrating trying to find it.

Just came across this one: Tour To Midgard: The Forgotten Land by Keith McArdle

OH yay you found it Sarah, Thank you so much :D

Yay!!
