Bling. The Lost Girls

Bling is book six in the Lost Girls series, a Dark Earth setting, by Jason HalsteadAmelia Foster makes a lot of bad choices. She's the hero of her own story, but her story has her caring for her ten year old brother and living in a homeless shelter in downtown Phoenix. For her, high school takes a backseat to working as an amateur contractor at a club most nights - it's the only way she can make enough money to try and save up for a better life for her and her brother.
Barely getting by takes a turn for the worse when she makes another bad choice and falls in with the wrong kind of friend. She's hurt and on the run from some dangerous people. She's a witness to multiple murders and the organization that's after her doesn't leave loose ends, even if it means kidnapping a child and using them as leverage to catch her. Amelia will do anything to save her brother but her options dry up faster than a summer rain in Phoenix.
She's left with one weak idea: reach out to a strange new friend from school that claimed to be willing to help... a friend by the name of Carmine Wimple, adopted daughter of the original Lost Girl, Katalina Wimple.  Look for these other Lost Girls stories:Book 1: The Lost GirlsBook 2: TraitorBook 3: WolfgirlBook 4: Black WidowBook 5: GuardianBook 6: Bling
