Hero by Anna Hackett

Fighting for love, honor, and freedom on the galaxy’s lawless outer rim…

Raised from birth to be a soldier, Kace Tameron is a disciplined, military-trained gladiator. He is on contract to the Kor Magna Arena to hone his fighting skills on the blood-soaked arena sand and then return to the military. He lives for one thing: to protect his planet, and on his world, love is forbidden. But then he collides with a feisty redhead from Earth who threatens to shatter his legendary control.
One moment, Rory Fraser was an engineer on a space station circling Jupiter and the next, she is abducted by evil alien slavers. After suffering at the hands of the Thraxians, she is rescued by her friends—with the help of the tough gladiators of the House of Galen. Rory finds herself outrageously attracted to straight-laced Kace. He is a skilled fighter, ultra-disciplined, and a hero at heart—but she knows passion beats within him, if only he’ll let it loose.
Rory is obsessed with finding another fellow abducted female from Earth, but as she asks questions, she finds herself ducking bullets and explosions. Someone wants Rory dead. Kace steps in as her protector, and together, they embark on a dangerous mission that will take them deep into the bowels of the arena, and deep into a scorching desire…both of which could lead them to lose not only their guarded hearts, but their lives as well.

Note to readers: This sci fi romance contains a lot of action (think wild gladiatorial fights and daring rescues), tough gladiators (the warriors of the House of Galen) and a steamy romance (between a feisty engineer and a disciplined, uptight gladiator). So if you like it fast, and gritty, and sexy, this is for you!
