Beyond - Beyond, #1

Book 1 of a 14 volume saga, ranging from the deep past to the distant future. Book 1 is the story of an unusual type of First Contact; one with a community that speaks English and looks human. It isn't NASA or ESA that meets the visitors; it is two young men who meet them. It isn't in a space ship or a time machine, but instead in a rural English pub. At first, it seems that the visitors can perform magic, but then, any sufficiently advanced technology looks like magic.
Two engineers, Paul and Geoff, return with the visitors to their hidden village and find a community that is a mixture of stone-age and ultra-advanced technology. The two young engineers save the villagers from extinction, and try to equip them to live in the 21st Century world."Beyond" sets the scene for a saga that covers 20 years, but stretches back 66 millions years and forward 30, 000.
