The Time Travel Chronicles
The 6-book series features 16yo street-smart Madison Bryant and science genius Riley Sinclair who travel through history in a time machine.
The first trip they take – to Ancient Egypt – is a choice. The second is driven by necessity to fix a problem they created on the timeline. But that fix creates still more problems which require more trips and fixing. Until the world’s time continuum is all mixed up like pirate stew.
They meant to tread lightly through time. But instead they’re leaving giant yeti-like footsteps behind them. And the rest…is no longer history.
