Sometimes you just have to cleanse your palate with an old favourite, and this lovely book by the great Neil Gaiman is just that.
Gaiman wrote the screenplay of the BBC series first (in the 1990s), and then the novel is an adaptation/companion to that. I love the series and re-watch it every couple of years and the same for the book.
Set in London below and with clever word plays (or real meanings) of many of the familiar London place names (whitefriars are actual monks, Knightsbridge is a scary bridge through the night, the angel Islington is an angel etc. ) a man from London Above (Richard Mayhew) is drawn into an adventure below when he stops and helps Door, a young woman on the run from two gloriously and humorously wicked thugs, Mr Croup and Mr Vandemar.
One of the first and best urban fantasies, this book fills me with warm, fuzzy, nostalgic, book love.
