Alluring Darkness by Nelly Alikyan

Can three new witches find their mother’s murderer?
Vera’s always been alone.
With her father gone, she’s left completely on her own until the magic in her finds a book of spells that takes her to two younger sisters she never knew she had.
Camilla loves her life the way it is.
But then she finds out she has another older sister, and with that sister comes the revelation that the supernatural world is real, meaning Camilla will have to leave her old life of being a normal human behind.
Maya’s always been fascinated by the darker side of life.
So finding out she’s a witch? Exciting. Unlike the hesitancy her baby sister holds at leaving her normal life behind, Maya is ready to jump all in.
The girls must now navigate this new supernatural world that comes with a warlock mentor, attacks from—attractive?—demons, and the possibility of romances that just may not be allowed.
And worse off, their mother’s death may not have been a natural accident, but a result of an attack from the supernatural world.
