There are musical goings-on at Ghastly-Gorm Hall and another spooky mystery for Ada Goth to solve in Goth Girl and the Sinister Symphony, the fourth book in the Goth Girl series by Chris Riddell, Children's Laureate 2015-2017.

Lord Goth is throwing a music festival at Ghastly-Gorm Hall, with performances from the finest composers in the land. Ada can't wait, but it's quite distracting when her grandmother is trying to find her father a fashionable new wife, there's a faun living in her wardrobe and Maltravers is up to his old tricks. Ada must make sure everything goes to plan, and luckily help is at hand from a very interesting house guest . . .
