There are musical goings-on and a mystery for Ada to solve in Goth Girl and the Sinister Symphony, the fourth beautifully illustrated adventure in the series from Chris Riddell, 2015–2017 Children's Laureate and author of the Ottoline books.

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. And there's a faun living in her wardrobe.

Worst of all, Maltravers is up to his old tricks and Ada must make sure everything goes to plan. Luckily, help is at hand – from a very interesting house guest . . .
