In the year 2050, Earth was on the brink of collapse. Pollution, deforestation, and overpopulation had left mankind's fate up in the air. There was no hope, that is until something extraordinary happened. Scientists discovered a wormhole to Mars. After much deliberation and endless research, the decision was made to start over, by colonizing Mars. Flash forward 107 years later, humans are thriving in an enclosed colony on the planet. 17 year old Owen Grey is the son of the colony's Commander. Adventurous yet reckless, his father is concerned about his perceived lack of a clear direction in life. Then, something else extraordinary happens. Reed Shepherd, an optimistic biologist proposes a mission, led by him, back to Earth to answer the question, "Has Earth changed for the better...or for the worse?" Last Call for Earth is a story about friendship, hope, survival, bravery, love, family, and above all, the complicated relationship between father and son.
