Phoenicia’s Worlds [EPUB ebook] 

Earth’s Colony Has Only One Chance Of Survival La Nueva Temporada is Earth’s only extrasolar colony – an Earthtype planet caught in the grip of a very Earth-type Ice Age. Alex Mateo wants nothing more than to stay and contribute to the terraforming of his homeworld. But tragedy strikes the colony, and to save it from starvation and collapse, Alex must reluctantly entrust himself to the Phoenicia, the only starship in existence, to make the long slower-than-light journey back to Earth. But it is his brother Quin, who loathes La Nueva Temporada and all the people on it, who must watch his world collapse around him and become its saviour… while everyone watches the skies for the return of the Phoenicia.
