Mark and Kim, who have lost the rest of the group, are left with the wounded Ling-Li. Luckily, Alexa quickly meets up with them and they're on their way to the sea again. But when the governor and Father Loomis catch up, they're taken straight to the mantris. The Betelgeuse Planet - also included in this two-volume edition - takes the theme of the colonisation of space further than most sci-fi comics by looking at its ecological aspect as Leilah Nakad studies the Lums, cute creatures that live on the planet Betelgeuse.
