Description

This novel is based on that we have destroyed our planet by WMD, and that there are not many of us left, and it is no longer sustainable.
We explored and found another planet, but several primitive intelligent life forms exist there. To avoid contact, we have built a secret staging base in a large mountain cave to explore for other suitable planets. During a supply run, the spaceship develops a fault and crashes far from the base, and the two survivors must trek across the landscape to reach its safety. The trek is the start to the novel, as it progresses with travel to other planets with less and more technological advancement than our own. This leads to planetary wars, not just to save humanity and others, but to bring sustainability to all our galaxy inhabited planets. It uses facts to make the non-fiction contents plausible.
The novel delves into; religion, morals, sexuality, sustainability, and it details relationships, with love between aliens with adult content.
