A Time of Shadows (Out of Time #8)

It's been a few months since Simon and Elizabeth returned from their adventure in 1888 London. Jack is back with them and all is as it should be, until a knock on the door changes that. A visitor from the future turns their world upside-down.

Unable to return her to her time, they go to the Council for help, only to discover there are bigger problems afoot. All of the watches have been shut down until a dangerous and secret weapon--a watch that can change any point in time--can be found. Too powerful for anyone to possess, it was hidden. But now the secret's out, and the mysterious Shadow Council will do anything to get their hands on it.

Simon, Elizabeth and Jack race to find it before the Shadow Council does or it will be the end of...everything.
