Sunset Empire

She may be guilty of arson, but she didn't kill the burned girl haunting her.

Elyse Pthan blames herself for her father's death. She stayed out past her curfew, and he was killed in a car accident when he went out looking for her. After the funeral, her house burns down, and Elyse is accused of setting the fire. Homeless and worried for her daughter, Elyse's mother moves her family to Astoria, Oregon to live with the strict grandmother they never knew.

Enraged by her grandmother's rigid rules, Elyse discovers the terrible heritage her mother kept hidden. Her family may be responsible for the 1922 fire that nearly destroyed Astoria, the death of a girl who longs for vengeance as she haunts the tunnels beneath the city, and mysterious disappearances spanning hundreds of years.
Helping her uncover the truth is Phantom, an enigmatic and surprisingly attractive boy, considering his scars, his talent as a pickpocket, and his status as the local social outcast. A boy with a hidden weapon and a dark heritage of his own, that could turn him from friend to hunter.
