5 book, 1 theme, a singular variety of topics
A young man with a boring job and a somewhat boring girlfriend , takes a shortcut while on an errand in London, after which he is to atrend to said girlfriend on a shopping trip. Suddenly, an older man accosts him, claiming to be his GGF. The only thing Kit, the young man, knows about this personage is that he left his home to run am errand and was never heard from again, leaving jis family destitute. He isn't much inclined to view thos ancestor credibly, bit then, somehow, he finds himself no longer in.a Lond9n alley, but in a seashore town complete woth sailing ships & people dressedn8n 19th century clothing. After he throws up and gets settled, he tries to convince himself this is one of those tourist traps where people re-enact how folk lived in an earlier time. His GGF tells him he is actually in the 19th century on an alternate dimension. Kit finds himself getting a crash course in ley lines, which his grandfather claims they traveled to get to the village. He then sees his GGS home to the alley in modern day London. Kit gors straight to his girlfriend's house. She is angry because he is 8 hours late. He tells her what happened but of course, she doesn't believe him. Since, when he amd his GGF traveled, they could see the town in the distance before they entered it, he takes her to the same alley, trying to show her, but the pull of the ley line is stronger so he is oulled bacl to the village, but since she wasn't in contact with him, she was thrown into 17th century Bavaria. A baker, laden with the tools of his trade, picks her up. It turns out this young woman spoke German in her childhood, with her grandmother, as they baked together; the young man is a younger son of a baker but there is no way for him to make it on his own unless he tries to set up in a new place. The young woman, Mina, works at a bakery back in London. She surprises the reader and the baker with unexpected skills in bargaining & marketing, including sending Etzel, the baker, on a trip to find coffee beans to start a coffeehouse in Prague, where they have their shop. Despite her finding herself seemingly abandoned 4 centuries oit of her time, the whole enterprise feels right to her and she blossoms. Meanwhile, Kit has gone to find his GGF to try to locate Mina.
Thus begins a series of 5 books that has a villainous and very wealthy enemy, and includes trips to the Etruscan kingdom (now Tuscany), Macau, ancient Egypt, the steppes of Eastern Europe, Constantinople, the stone age, Arizona & New Mexico, Oxford, Damascus on the 1930s, and more, as other characters accidentally discover ley travel. Kit visits the Well of Souls inadvertently, the place which an explorer called Arthur Flinders-Petrie (sort of the father of ley line travel, he has a map tattooed to his torso in Macau (so it can't be lost), in an odd code, and he adds to the map regularly; when he dies, his son asks for a copy of the map and because of a linguistic misunderstanding, ends up with his father's skin instead). This man encoded on his body the location of this well of souls but the code is so obscure that no one can decipher it.
Then things start going wrong. The expanding universe has stopped expanding and is contracting at an ever increasing, alarming rate. As each dimension destabilizes, the rush is on to find out what might have triggered the reversal and how it might be stopped, as different teams of ley line travelers have to travel through ever more umstable ley lines to try and stop the damage. Throughout this, they have to deal with the villain - until he goes too far and he and his hemchmen end up rotting in jail. The baker, whom the villain attacked & injured severely, ends up feeding the prisoners - something done by friends and family but not by the jail, forgiving then because Jesus forgave him. The henchmen are soon separated from the villain since they have come around to rethinking their lives due to the baker's kindness, but it takes the villain quite a long time to come around. Once he does, he still shows a lack of understanding & has to be stopped by the others be d ire he does more harm in trying to fix things best left to Jesus.
Although the Creator is mentioned by that title soecifically throughout the book, it is mostly in the background, though you do see priests and church people from time to time. The only mention of Jesus is in the last book in the compendium, as the faith soecifically of one man. The rest of the mentions are more philosophically oriented and always as an individual choice, not a thing to be forced.
The author brings in elements of hisotry, language (17th century English, for example, is difficult to understand by even Kit's Victorian GGF, and Kit has difficulty understanding both Victorian and 17th century English becaus words don't mean the same thing to speakers in amvarious eras, plus German, French, Latin, & others. He also brings in a lot of science, starting with the 13th century's scientists on.
