Publisher's summary
When the evil Skelloids launch an attack upon the seventeen worlds of the Generios system, its peace-loving inhabitants face total destruction.

So it's lucky that the Doctor, that famous traveller in time and space, is in the area, and that he, along with his pretty young assistant, Sally-Anne, manages to defeat the deadly creatures and save the day.

But now it looks as though the Doctor's luck has run out.

Who is the mysterious, curly-haired stranger, intent on causing trouble? What role does the feisty redhead Melanie play in his scheme? And what have they to do with the sinister alien cylinder approaching Generios?

One thing is certain: for the Doctor and Sally-Anne, there's deadly danger ahead...
