Private eye John Taylor must travel back in time to stop his mother destroying the Nightside, the secret heart of London. Things are about to get complicated . . .

John Taylor was born on the Nightside, where it is always the hour of the wolf, where gods and monsters walk side by side and where every dark question ever asked can be answered - for a price. Unfortunately, the answer he'd long been seeking came with trouble: he found out his mother's true identity - and discovered that she created his home, the twisted, noir playground known as the Nightside. That means she has the power to destroy it. Turns out, she's also got the will.

Taylor's convinced that the key to stopping his mother lies deep in the past, in the days of the Nightside's creation, so that's exactly where he's headed. But travelling through time is a dangerous business, and the past can be a deadly place*.

Paths Not Taken* is the fifth title in Simon R. Green's New York Times bestselling Nightside series.
