Secrets of the Nile - Paulene Turner

If you're reading this, it may mean I don't exist any more. Time travel's like that. Here today, erased tomorrow.

Madison Bryant, 16, is escaping an awkward romance when she leaps into her friend Riley's latest invention--a time machine--as it blasts off on its maiden voyage to Ancient Egypt. Setting down by the Nile in a swirl of sand, the pair plan to stay for a day or two and observe, not interact with anyone. But when a local girl invites them to her family home, they're drawn into village dramas and can't resist using their future knowledge to help.

An epidemic of dental troubles? Riley introduces toothpaste to the ancient culture. The vizier's teenage son drowning in a hippo-filled river? Maddy rescues him using life-saving techniques acquired on a Sydney beach.

Sure, she's read time travel stories with those warnings about not changing the past in case it changes the future in unpredictable ways. But they don't apply to her. She's just an ordinary girl--a mere speck of sand in the vast desert of time. And nothing she does could ever shift the course of the world. Could it?

Secrets of the Nile is a high-stakes fast-paced adventure in mysterious Ancient Egypt. It is book one of six in The Time Travel Chronicles series.
