Kepler 62 Book 4: The Pioneers

Only two of the space vessels reach their final destination, but the lush, green planet that they land on is more suitable for life than anyone could have imagined. It's like a paradise compared to the barren Earth they left behind. Once the children start building their base camp they find traces of other forms of life. Will they be friendly or hostile? Meanwhile, Ari and Marie are becoming increasingly disillusioned by Olivia's secrecy surrounding the mission. And when Joni falls ill, the children look for help elsewhere – with disastrous results.
