One For my Enemy by Olivie Blake

From bestselling author Olivie Blake comes an intricate web of love, magic, and rival witch families in New York City.

In modern-day Manhattan where we lay our scene, two rival witch families fight to maintain control of their respective criminal empires.
On one side of the conflict are the Antonova sisters — each one beautiful, cunning, and ruthless — and their mother, the elusive supplier of premium intoxicants, known only as Baba Yaga. On the other side, the influential Fedorov brothers serve their father, the crime boss known as Koschei the Deathless, whose community extortion ventures dominate the shadows of magical Manhattan.
After twelve years of tenuous co-existence, a change in one family’s interests causes a rift in the existing stalemate. When bad blood brings both families to the precipice of disaster, fate intervenes with a chance encounter, and in the aftershocks of a resurrected conflict, everyone must choose a side. As each of the siblings struggles to stake their claim, fraying loyalties threaten to rot each side from the inside out.

If, that is, the enmity between empires doesn’t destroy them first.
