Summer Wright organises her life down to the minute. And when boyfriend Adrian proposes marriage - on schedule - she will reach the peak of The Cone of Certainty. At least, that's the plan - until adventure-show queen Cougar Gale intervenes. Suddenly Summer is impersonating Cougar in Antarctica: learning climate science on the fly, building an igloo, improvising scripts based on Dynasty, and above all trying not to be revealed as an impostor. But Summer finds it particularly hard to fool climate scientist Lucas Nilsson. Can Summer use her extreme project management skills to get Project Adrian back on track and make a success of "Cougar on Ice"? And what is The Krill Question anyway?
