The short second life of Bree Tanner : an Eclipse novella

Summary: "BREE TANNER CAN BARELY REMEMBER LIFE before she had uncannily powerful senses, 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 your 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 only know as her. As they come to realize that the newborns are pawns in a game larger than anything they could have imagined, Bree and Diego must choose sides and decide whom to trust. But when everything you know about vampires is based on a lie, how do you find the truth? IN ANOTHER 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 and the Cullens, following their encounter to its unforgettable conclusion." -- goodreads.com
