Dead Dead Girls by Nekesa Afia

Louise spends her days working at Maggie's Cafe and her nights at the Zodiac, Manhattan's hottest speakeasy.

When a girl turns up dead in front of the cafe, Louise is forced to confront something she's been trying to ignore - several local black girls have been murdered over the past few weeks.

After Louise's night job gets her arrested, she's given an ultimatum: She can either help solve the case or let a judge make an example of her.
