Here is a synopsis of the first book Out of Time
It’s 2015 and the Martians are about to invade Earth. They have hacked into the Earth’s social media companies and absorbed them into the media site ComsMesh to manipulate the human race and weaken its defences. Up to now no one on Earth suspects a thing.
Then, one of ComsMesh staff finds the 2015 diary of a James Urquhart, and the 1873 diary of Elizabeth Bicester bound together in a copper chest and concludes they are actually time travellers. He flags this up to his director as he believes such technology in the wrong hands could reveal his Company’s plans to socially engineer the world.
So here are the diaries of the adventures of James Urquhart, minor science lecturer and sometime rambler, living in 2015 and Elizabeth Bicester, lady of leisure, of Hamgreen Lodge whom he stumbles upon at a cricket match in 1873. Despite much banter regarding each other’s etiquette and manners it seems they manage (through incredible feats of illogical deduction, with not a little help from James Maxwell, H. G. Wells and some strange time devices) to save the world.
As this story developed, Wells became a more and more important charcter for the reasons I’ve described here.
