The short second life of Bree Tanner - Stephenie Meyer

I turned off my brain. It was time to hunt. I took a deep breath, drawing in the scent of the blood inside the humans below. They weren't the only humans around, but they were the closest. Who you were going to hunt was the kind of decision you had to make before you scented your prey. It was too late now to choose anything.

Bree Tanner can barely remember life before she had uncannily powerful sense, superhuman reflexes and unstoppable physical strength. Life before she had a relentless thirst for blood. . .life before she became a vampire.

All Bree knows is that living with her fellow newborns has few certainties and even fewer rules: watch you back, don't draw attention to yourself and, above all, make it home by sunrise or die. What she doesn't know: her time as an immortal is quickly running out.

Then Bree finds an unexpected friend in Diego, a newborn just as curious as Bree about their mysterious creator, whom they know only as her. As they come to realize that the newborns are pawns in a game larger than anything they could've imagined, Bree and Diego must choose sides and decided whom to trust. But when everything you know about vampires is based on a lie, how do you find the truth?

In an irresistible combination of danger, mystery and romance, Stephenie Meyer tells the devastating story of the newborn army as they prepare to close in on Bella Swan in the Cullens, following their encounter to its unforgettable conclusion.
