Book Four in the Altered States series.

An analyst in a secret government agency, Casey McTaggert has dedicated her life to the capture of one suspected terrorist. Even before she's abducted in the midst of a firefight, she's completely fascinated with the man called the "The Tiger". But what began as a professional obsession quickly becomes lust as his dark features and harshly hewn body awaken a forbidden passion.

Khalid Razeh can't fight the genetic programming that makes him shift into a tiger any more than he can resist the sensual allure of his lovely hostage. While forcing her to accompany him on one last mission, he fights his overwhelming attraction, knowing he is walking into a trap that will end in death. Casey's tender lovemaking and growing belief in his innocence are a sweet balm to his wild, savage soul.
