Mirabelle In Double Trouble

Mirabelle is going on holiday with her family to a fancy witch resort and she can't wait! She has promised her parents that she will absolutely not get up to mischief this time. And she really means it too.
The witch resort is everything Mirabelle had hoped for, and more! Better yet, she makes a new friend called Bea. Then Mirabelle makes a worrying discovery-Bea is even more mischievous than Mirabelle, and she quickly finds herself in a whole heap of trouble . . . especially when a dragon gets involved!
Will Mirabelle's family believe that Mirabelle is (mostly) innocent this time or is it just a case of double the trouble?
