A Discovery of Witches

It started well, but then it seemed the story dragged on and on and on... I liked the yoga class with witches, vampires, and demons. There was a lot of world-building info dump that threw me off the plot. Some characters are vampires who lived for centuries, so there was too much background story delivered all at once. I can see it was well researched, mentioning old editions of Bibles, the works of Galileo, Isaac Newton, and Darwin, for example. The writing just didn't flow well for me, I wasn't invested enough in the characters to want to follow them through the next two books.??
