When Rainbows Cry

Petra Sucher's having a really bad week. Her week is about to get even worse. She's about to lose her 4 year old brother, time travel and possibly end civilisation as she knows it.

Hopefully the mysterious object she finds in the Natural History Museum will help her set things to rights. Or perhaps the interesting Octogenarian she spotted there.... Or possibly the genetically engineered chimpanzee she's about to meet...
