Last Hope: Mankind's Final Chance to Prolong Our Species By Finding New Planets to Inhabit (ePub)

This novel is based that we have destroyed our planet by WMD war and there is not much of humanity left, or anything else. Vegetables for food are grown under cover and we scavage for tech and other essential supplies to build spaceships to escape.
Our mission is to find another planet to live on as ours is no longer sustainable. One was found that may be suitable but it has several primitive intelligent life forms that exist there and a supreme galaxy entity watching over them and everything else but it needs help. To avoid contact with the incumbent habitants a secret staging base was constructed in a large cave high up a mountain.
During a supply run, the spaceship develops a fault and crashes far from it. The two survivors must trek across the treacherous landscape to reach it. The trek is the start of the novel, as it progresses with travel to other planets with less and much more technological advancement than our own.
Planetary wars break out, and the mission is to save humanity and other alien lifeforms. The overall objective is to bring peace and sustainability to all of the galaxy-inhabited planets.
The novel uses facts to make the non-fiction contents plausible reading and delves into; religion, morals, sexuality, LGBT, and sustainability. It details relationships of love and sex between aliens with adult explicit content.
