The Incorrigibles go to London
In this book our friends Alexander, Beowulf, and Cassiopeia Incorrigible and their awesome governess Penelope Lumley go to London along with Lord and Lady Ashton. Penelope has never been to London and thinks about all the educational things the famous city has to offer. Read about all the interesting things the children, Penelope, and their new acquaintance Simon Harley-Dickinson do in this city. Meanwhile, what is Penelope's friend and former teacher Miss Charlotte Mortimer so worried about?
Intense and Involved
Like others said, this is a great series but is dark and not for the faint of heart.

Definitely read the books BEFORE you watch the show. The book is extremely complex and detailed, and I expect to re-read the series a few times to grasp everything that is going on. I have only seen the first season of the show, but I was impressed with how they condensed it.
