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 . . .
