'A laugh-out-loud funny and exciting adventure!' Cressida CowellFrom the incredible imagination of Chris Smith - bestselling author and now a major new solo talent - comes an extraordinary accidental adventure for fans of Cressida Cowell and Pixar's Onward. Frankie Best is not happy. She's stuck at Grandad's with her annoyingly nerdy brother Joel for a whole week while her parents swan off to the Arctic.

Things take a turn for the worse when Grandad gets kidnapped by gnoblins (no, that is not spelt incorrectly) forcing Frankie to embark on a rescue mission across a magical realm filled with strange creatures, dangerous enemies and - worst of all - absolutely no WiFi. Frankie did have big plans to watch YouTube and eat pot noodles that weekend but it looks like she'll just have to go on an epic mega-dangerous quest instead . .
