Set in a modern London with a severe ghost problem, this is the second adventure for the intrepid phantom stalkers of Lockwood & Co. Brought in at the discovery of an unexpected grave, the disinterring of the iron coffin and its grisly contents leads to disaster, and a dangerous ghost escapes and an even more dangerous artifact is lost. Even more dangerous than the supernatural entities are the living villains sniffing around - relic hunters looking for haunted objects to steal and sell. Lucy, George and Lockwood tear around London on the trail of the mysterious mirror, but there's a killer close behind.

This series is becoming a favourite. Rich in atmosphere, lots of secrets and mysteries and plenty of adventure and intrigue all built around endearing characters. Exceptionally well written, too, dark and witty, but surprisingly ordinary and cheerful in its everydayness. Of the three YA books I've just read and reviewed, this was the most fun, which is surprising when you consider how preoccupied with death a smart book about ghost hunting must necessarily be. But with no genocide and no series of brutal betrayals and compromises corrupting their souls, Lockwood & Co are definitely the people to hang out with.
