Ripple (Breakthrough Book 4)
It began in Ethiopia, hundreds of thousands of years ago.  When a handful of genetic mutations caused evolution to split from the primates.  And mankind was born.<br /><br />Now, eons later, evidence of more splits from the apes are being unearthed. And with them, a disturbing realization. <i>Ours </i>was only one of many.<br /><br />And yet we survived. But it was not by luck or chance. We survived because humans had something the others did not. A unique ingredient that has only now been rediscovered.<br /><br />First in the mountains of South America, where it was promptly destroyed by the Chinese. And now a second source in Africa. The epicenter of mankind's very inception.<br /><br />A place that John Clay and Alison Shaw must find quickly. Because the Russians already know what we are searching for. And the Chinese want back what is rightfully theirs.<br /><br />The mother of all secrets awaits the world, in Africa. One that will not only explain who we are, but will decipher the very code within our own DNA.
