13-year-old Billy is on a school trip, visiting the British Museum, when he slips back in time and joins his grandad for a good old-fashioned dose of derring-do and dastardly deeds. The Al-Eden Emergency features classic aircraft and cars from the mid-20th century as well as some jolly good chaps and a couple of thoroughly bad eggs.

It's 1966 and Billy's RAF officer Grandpop is something hush-hush in the Ministry of Defence. All eyes are on the port of Al-Eden, a hothouse of rebel activity. As soon as Billy lands on its barren rocks, he's thrust into a storm of intrigue. He discovers: a secret terrorist organisation led by the enigmatic "Scorpion", Al-'Aqrab, a stolen astrolabe linked to a mysterious prophecy, an aircraft carrier sailing on shark-infested waters and a good friend who's being held against his will – or is he? Meanwhile, an old enemy is closing in. Can Billy crack the puzzle before his cover is blown?

The Al-Eden Emergency is the cracking third instalment in S.P. Moss's series of retro-style adventures. "Al-Eden" is a fictitious place, but is inspired by Aden, where the author lived as a small child in the 1960s. Fans of the previous books, as well as any 10 - 13 year old who enjoys breathtaking adventure, will be thrilled by this tremendous tale!
