Dangerous Nights/Shadows in the Night/Out of the Darkness by Heather Graham

Shadows In The Night

A year after the chilling death of her mentor, criminologist Harley Frasier is still rattled. Secretly she’s suspected murder all along. Now the unveiling of the Amenmose exhibit is triggering a series of unexplained attacks, and she has only one man to trust.

FBI special agent Micah Fox is used to charging into dangerous territory to solve a case. But working with a civilian is new ground, especially when she’s as irresistible as Harley. He can’t say no to her sharp instincts and sexy smile. And with a threat closing in, there’s no way in hell he’ll leave her unprotected.

Out Of The Darkness

Even after a decade, Sarah Hampton is haunted by the night that nearly ended in a bloody massacre and destroyed her high school romance with handsome Tyler Grant. Now the horror has returned. It’s a reckoning from the events of that terrifying night — and a love they never let go. Only this time Tyler must protect Sarah from the killer hiding in the darkness...or lose her forever.
