'Adventures happen to people who need them. Whether they want them or not is entirely beside the point...'
When risk-averse, adventure-hating Casper Tock stumbles into Rumblestar, an Unmapped Kingdom full of magical beasts, he wants to go straight home.
But Rumblestar is in trouble as Morg, an evil harpy, is trying to steal all the Unmapped magic for herself.
Together with Utterly Thankless, a girl who is rule-averse and allergic to behaving, Casper sets off on an adventure.
Can these unlikely heroes save the Unmapped Kingdoms and our world from Morg and her followers, the Midnights?
