Ripples

Many will die if you fail; some will die if you succeed...

A few years have passed since Samantha and the crew of the Hermes escaped the destruction of their home planet. They left as children. They have had to grow up fast.

Since they tracked down the Pandoomans, the advanced species that has been intervening in Earth's history for millennia, Samantha and her friends have learned that most have done so with the best of intentions. Most, but not all. For a small group of rebels will stop at nothing to make sure that the human race will never inherit the Great Knowledge that the elders of their dying species want to pass on.

In their toughest mission yet, Samantha and the crew return to their ancestral planet, bouncing between eras in a desperate race against the rebels, never knowing what they will face next or who might fulfil the oracle's latest ominous prophecy. All the time, they're painfully aware that at any moment, history could pivot and they, along with the entire human race, would cease to exist.

Ripples, the fourth book in the action-packed sci-fi series Serendipity, takes the reader on a nail-biting journey through history. Will our heroes win the battle over time itself?
