Stolen memories, a lost diary and a race against time...

Having saved Princess Evelyn (and become her new BFF) Sam must accompany Evelyn on a world tour, so she can keep the princess (and everyone around her) safe with a power-binding potion. But Sam also has another reason to scour the globe. Someone has tampered with her grandad's mind, and Sam is the only one who can unlock his memories to save him and the family business. And that's not all that's at stake. The stolen memories contain the recipe to a potion which many would kill to get hold of. With the post powerful people in the world desperate for the recipe, Sam must save her grandad in order to save everyone else...
