In Returning Left Luggage, Book Two of the ARIA Trilogy, we finally meet the aliens. Unlike most science fiction aliens, these ignore the remaining humans, or make use of them for labour. They don’t bargain on encountering the psychotic Dr Antonio Menzies, and when he discovers how to use their telepathic-controlled gadgets, odd things happen.

Meanwhile Ryder’s isolation group are in the South Pacific facing invasion problems of another kind. That, and trouble in the French Alps, along with a runaway exotic weed, makes this sequel one you’ll not want to miss.
