On Silver Wings
by Evan Currie
https://www.amazon.com/gp/product/B005QOX3ZY/ref=series_rw_dp_sw

When the Colony on Hayden's world went black, a team was sent to investigate. It was supposed to be a training mission : skip in, find out why the Casimir Transmitter had gone dead, report back and wait for resupply from the Fleet. By the time the only surviving member of the team made landfall, it was spectacularly clear that this wasn't a training mission.
Now Sgt Sorilla Aida has a job to do. She has to gather the local survivors, recon the enemy, train a militia, and take the war right to the enemy's doorstep.
Just what she trained for.

Island in the Sea of Time
by S. M. Stirling
https://www.amazon.com/gp/product/B002JF1N28/ref=series_rw_dp_sw

A cosmic disturbance transports the island of Nantucket and its inhabitants over three thousand years back in time to the shores of a Stone Age America. In addition to coping with the day-to-day problems of survival and the trauma of losing all connection with the modern world, the residents of the time-stranded island find their lives complicated by the presence of native tribes across the water.
