The Affinity Bridge by George Mann
Leaving out all the book info junk. Chris and I are reading this book simultaneously. We're only 8 chapters into it, but it's pretty interesting thus far. Sleuths Newbury and Veronica are solving the puzzle of a zeppelin crash in London during the Victorian era. Said zeppelin was piloted by an automaton (i.e. robot) and it was not found amongst the wreckage. There also appear to be zombies in this book and we don't know how everything is connected (yet). So far I'm really enjoying it and glad to be sharing it with my partner in crime, as it gives me a chance to read a Victorian mystery, which he loves.
Always looking for more books to read. Send in suggestions if ye have any.
