Tainted

They've unleashed something they don't understand...
Mia Sanchez has done the impossible, infiltrating the San Francisco headquarters of the mysterious Genesis Foundation. As a secret agent of Department 51, she’s their best hope of finally bringing down the well-funded organization and reclaiming the extraterrestrial tech they’ve been using to clone perfect children. Her opportunity wouldn’t have been possible without the help of Dr. Noah McMann. 
Noah’s belief in the core mission has been faltering since he made contact with Juliet Manning, their first perfect subject. As the head doctor overseeing the cloning of embryos, Genesis won’t allow him to leave alive. He had come to accept his fate, until the impossible birth of Lyric and Lexicon.
Using the Telomere Stone that Genesis recovered from extraterrestrial wreckage, he’d mapped the DNA strand for another female embryo. Twins should have been impossible. More unexplainable than their birth, doctors studying them have started dying. With every secret Noah and Mia uncover, the more convinced he becomes of one undeniable truth. Something in their DNA is tainted, and if he and Mia don’t stop them soon, the entire world could bend to their power.
