Will Hallam - Hop 2 Mercury - Tracey Dickson - Bog

What is TILOAPS? All Amy knows is that the word refers to a pact Will Hallam made with his old friend Zac. Circumstances tore the friendship apart but the pact was never forgotten. Now Will's experiment with a magnifying glass sets Will, Amy and her dog Pat off on an epic adventure to Planet Mercury where the Tronbeings are at war. The trio can't go home again until they bring peace to the planet.... and somehow that's to do with the mysterious TILOAPS.
