Dead Banshee by Elizabeth Hazelwood

One wants the other dead. The other just wants blood.
Brielle Strong knows when someone dies–and thanks to her wails, so does everyone around her. No one likes her wails, Brielle least of all. The only thing her wails are good for are taking out vampires. So, as much as Brielle hates her wails, she needs them.
A blood-addict vampire with skin like melted candle wax killed Brielle’s younger sister–and Brielle wants revenge.
To make matters worse, Brielle’s older sister is being targeted by the magical society she’s a member of. Shea Strong destroyed a rare artifact while exploring its secrets–and the Golden Lanterns aren’t happy.
If a new artifact isn’t made within twenty-four hours, Shea’s toast. Now Brielle has to infiltrate the society she’s never wanted to join, with the help of a grim reaper who struggles with not knowing what happens to the dead after he takes them to the other side, a healer who lost his powers after failing to heal Brielle’s sister, and a retired vampire hunter who’s terrified of vampires.
The vampire who killed the third Strong sister has a talisman that protects her from dangers like Brielle. If Brielle can get the talisman away from the vampire, she can end the wrinkled creature.
All she has to do is wail.
