In the near future, as America endures its second Great Depression, former Navy SEAL Shane Laughlin finds work as a test subject at the Obermeyer Institute, only to be plunged into a strange world where mild-mannered scientists can kick his highly skilled ass. These "Greater-Thans" undergo rigorous training to master unique abilities--including telekinesis, super strength, and reversal of the aging process--by accessing untapped regions of the brain. But for the rich and reckless, there's a quick, seductive alternative: Destiny, a highly addictive designer drug that can make anyone a Greater-Than--for a lethal price. Michelle "Mac" Mackenzie is determined to end the scourge of Destiny. As one of OI's crack operatives, she's learned to wield her powers responsibly. But she's knocked for a loop when she meets the new test subject: Shane, the same smoldering stranger who just rocked her world in a one-night stand. Mac's got reasons to keep her distance from him--and reasons that are just as strong to want him close. She's used to risking her life, but now, in the midst of the ultimate war on drugs, she must face sacrificing her heart.
