Dr. Raleigh Foster, an operative for a top-secret intelligence organization, knows that her undercover work has its risks. So she doesn't hesitate when asked to infiltrate Scimitar, the terrorist group that has stolen lethal environmental technology. But when she's assigned a partner—brooding, sexy Adam Grayson—to pose as her lover, Raleigh discovers that the most dangerous risk of all...is falling in love. Adam blames himself for the botched mission that got his best friend killed by Scimitar, and he believes that Raleigh may have contributed to the man's death. But the closer he works with his alluring partner, the more his suspicions turn to trust—and intense desire. Now, as he and Raleigh untangle a twisted web of secrets and lies, the tension mounts between them...until their masquerade as a couple proves too tempting to resist.
