An eccentric like all Helmsleys, eleven-year-old Archer escapes his overprotective mother and recruits two friends, Oliver and Adelaide, to help him plan a rescue of his long-lost grandparents, world-famous explorers who disappeared atop an iceberg in the Antarctic.

Visiting her grandmother in Australia, Livy, ten, is reminded of the promise she made five years before to Bob, a strange, green creature who cannot recall who or what he is.
