Nightfall — Robyn Bachar

Her heart says “never”. Her body says “now”.

When a wounded runner stumbles into her workshop, sculptor Talena Spenser's comfortable, quiet life is shattered. Aiding the escaped slave risks losing more than just her freedom. She is in phase, when Cy'ren females are overwhelmed by the drive to mate.

Mordacki Loren, shadow sword of House Nightfall, knows the pain of losing a mate. He never intended to take another. But Talena, raised by humans with little knowledge of Cy'ren ways, leaves him no choice. As the mating lust consumes them, Dack promises to honor her wishes -- even if that means letting her go.

Scarred and hardened by a munitions accident that sent her Alliance career up in flames, Carmen Hawke joined the Cy'ren resistance as captain of the flagship Talon. When old flame Dack returns from a mission with Carmen's childhood friend and first love, Talena, in tow, the temptation to allow someone -- or two someones -- close to her again cracks her emotional armor.

Pursued by an unknown enemy, the trio works together to discover the secrets of Talena's past, and to uncover a threat that could destroy the fragile peace of the Cy'ren homeworld.

Warning: If the epic space battles, gunfights and swordplay aren't enough to get you going, strap yourself in for a male-female-female threesome that's scorching enough to fire your engines into overdrive.
