Horizon Alpha: Predators of Eden by D.W. Vogel is a completely plausible future scenario for planet Earth and its inhabitants.
After fleeing doomed Earth for another earth-like planet, a group of survivors who happen to be low on adult men, have to rely upon a group of teenage boys to find a lost power source for their camp among ship wreckage in the jungle. They have to avoid creatures that they comparably deem “dinosaurs” as they carry out their search.
Although I enjoyed the story myself, and it’s worthy of a read by any demographic, it should be especially appealing to young boys looking for an adventure with a relatable hero.
