About NIGHT UNBOUND

For centuries, Lisette d'Alençon has been a warrior against the dark. She fights alongside her brothers and comrades. But when the dreams start coming, she can't bear to confess them to the Immortal Guardians' command. Dreams of a dark-haired man with soft eyes and brutal wounds, a man her heart aches for—and a man she knows has been declared a traitor.

Zach is an exile, a loner. He won't defend himself against false accusations or grovel to those who should have faith in him. But he'll damn sure defend the woman who kept him sane against a plague of super-vamps that seems to have appeared from nowhere. The Guardians will blame him, and that will make Lisette suspect, too. With life, death and eternity on the line, who can they really trust?

About DARKNESS RISES

Krysta is used to getting the drop on vampires. Her "special abilities" aren't much, but the plan is simple—she plays helpless pretty young thing to lure them in. Then her shoto swords come out and it's bye-bye, bloodsucker. Until one night she finds herself with an unexpected ally. He's a vampire, all right, but different. Mysterious. Handsome. And more interested in saving her skin than draining it.

Etienne has been an Immortal Guardian for two hundred years—long enough to know that Krysta is special. He can't stop thinking about her long legs, even more than her short swords. Then he discovers the vamps she's exterminating have friends in high places, and the Guardians are in danger too. He'll have to accept Krysta's help to save them. The stakes for a mortal are high. But the cost to his heart might be higher. . .
