Pink Water - The Cloud Brothers, #2

Unknown to all but a brave few, invading aliens have been defeated and sent home with a bloody nose. Unknown to everyone, the revengeful aliens left two booby traps. When triggered, one trap will melt the polar ice caps, causing the sea level to rise seventy meters. The other trap has already removed the only people who can save the earth, whisking them away in a wormhole. The wormhole goes wrong, leaving Trevor, Russell, and an icebreaker with its motley crew trapped inside.
Lost in space and time, Trevor and Russell must return with the antidote and attempt to navigate back through the collapsing wormhole. Their treacherous journey fails. On the verge of death, unexpected help materialises. The price? Everything they own and a profound change of attitude.
