Arthur (Art) Mumby and his irritating sister Myrtle live with their father in the huge and rambling house, Larklight, travelling through space on a remote orbit far beyond the Moon.

One ordinary sort of morning they receive a correspondence informing them that a gentleman is on his way to visit, a Mr Webster.

Visitors to Larklight are rare if not unique, and a frenzy of preparation ensues.

But it is entirely the wrong sort of preparation, as they discover when their guest arrives, and a Dreadful and Terrifying (and marvellous) adventure begins.

It takes them to the furthest reaches of Known Space, where they must battle the evil First Ones in a desperate attempt to save each other - and the Universe.

Recounted through the eyes of Art himself, Larklight is sumptuously designed and illustrated throughout.
