Convergence - Kindred Ties, #1

For scientist Robyn Greene, her laboratory is a second home. Here she searches for the ancient gene that is supposed to enable humans to communicate with animals. After years of failure, she's beginning to wonder if the gene is a myth. But when she stumbles across a strange genetic mutation, Robyn's world turns upside down. The man posing as her boss is, in fact, an operative of the mysterious international organisation, the MRI.
Worse, they have dark plans to exploit her discovery. In a race against time, Robyn must track down the individuals with this rare gene before the MRI turns them into lab rats. But when she meets the three teenagers, she realises that protecting them from the MRI is not only about saving their lives. Fletcher, Ariana and Eli are capable of more than anyone realises; they are part of an ancient cycle designed to keep the Earth in balance.
A terrible future awaits the planet if the MRI gains control of Robyn and her research before she's figured out the kindred ties that bind these teenagers.
