Omnibus : Invisible and Timesnatch ( 2-in-1 Books )

Invisible: What would you do if you could become invisible? Creep around, unseen? Listen in to other people's conversations? Twins Carrie and Conrad, and their friends Peter and Charlotte do all these things, and much more, when a new girl at school - Rosie - shows them her secret: how to make yourself invisible. Timesnatch: Once a creature is extinct, it's gone for ever, isn't it? Not any more - as a butterfly from the past proves. The physicist mother of Kizzy Rye and Fraser Rye has invented an amazing time machine that can travel back into the past, snatch a plant or animal now extinct and bring it back into the present. It's a wonderful achievement, a real scientific breakthrough. But the machine - 'Rye's Apparatus' - has a horrifying potential. Suddenly Kizzy and Fraser find themselves caught up in a terrifying spiral of events - events that lead finally to a monstrous demand from a sinister and violent organization..
