This Mortal Coil

3 billion lives at stake. 2 people who can save them. 1 secret hidden in their DNA. A breathtaking debut series about one girl's quest for answers in a genetically and technologically advanced future. There's no gene for RUN LIKE HELL.
When a lone soldier, Cole, arrives with news of Lachlan Agatta's death, all hope seems lost for Catarina. Her father was the world's leading geneticist, and humanity's best hope of beating a devastating virus. Then, hidden beneath Cole's genehacked enhancements she finds a message of hope: Lachlan created a vaccine.
Only she can find and decrypt it, if she can unravel the clues he left for her. The closer she gets, the more she finds herself at risk from Cartaxus, a shadowy organization with a stranglehold on the world's genetic tech. But it's too late to turn back.
As the pieces fit together it's clear there is one final secret that Cat must unlock. A secret that will change everything.

With the pace and twists of a thriller, an emotional sucker-punch, the exquisite world-building of the best fantasy, and an imagined future that sci-fi fans will love, THIS MORTAL COIL has all the ingredients to become the next phenomenon in YA.
