When the Sun Blinked Book 2: The Soldiers

A world unimagined – the other side of the mountain range is as far removed from twenty-first century reality as a parallel universe. For the nine survivors the full extent of this pristine, wildlife-filled environment, is totally bizarre and an encounter with an unexpectedly large, but injured lion leaves them baffled - from a size perspective.
From the top of one of the numerous mountains, a puzzling sighting provokes more disturbing questions than answers. From another side of the same mountain, they can overlook the bay into which they crashed, but what they see, simply adds more confusion to the puzzle.
Making their way back to the other nineteen survivors, the information is shared, and a decision made to attempt to climb the massive mountain behind where they are living. If they can get high enough, it may bring the pieces of the puzzle together and either confirm or deny what they have seen.
What they see provides the answer to what they went looking for. And if it is correct, there is not going to be any rescue - ever - and this is their new world, for better or worse.
Searching for other survivors takes them down the coastline to the remains of another crashed commercial airliner. Breaking into the hold enables them to scavenge enough supplies to enhance their current uncertain world.
During the days of scavenging, they become aware that they are being watched from one of the mountains by seven armed men, dressed in the tattered remains of camouflage uniforms. These men, however, seem reluctant to come down and meet them, which raises suspicions in the minds of the survivors.
When they finally do meet, their suspicions are confirmed. They are all soldiers, survivors of the same event which caused their helicopters to crash, but now they see the situation as an opportunity to take over the original group and re-populate the world according to their rules.
A situation that cannot possibly end well.
