Hell Squad soldier Gabe Jackson has lost everything he holds dear, including his twin brother. Now all he wants is to kill invading aliens using every means he knows... and he knows a lot of them. Having been a member of a secret unit of super-soldiers, Gabe has become faster, stronger, more dangerous... however, in his soul he only has an accumulation of rage, pain and grief, which is just waiting for a chance to drag him to the bottom. But then he meets her. Dr. Emerson Green's whole life has been planned: hard work in the emergency room, career advancement, a great future. But suddenly an alien invasion began. Now she leads a team of doctors at a secret base near Sydney where survivors are taking refuge. In addition, Emerson patches up soldiers who get too close to the claws of predators. She never planned on this...just as she never planned on meeting the sexy, silent Gabe Jackson. As Emerson and Gabe get closer to unraveling the aliens' intentions regarding the human race, they find themselves caught in a storm of explosive passions. But the brooding soldier is as stubborn as he is silent, and she knows she must convince him to open up to her... because Gabe is a time bomb waiting to explode.
