Lonely Souls by Karice Bolton

It’s two weeks before Triss turns 18, and her world is about to change into the most magical one imaginable as she readies herself to enter The Witch Avenue Order... that is until her mother’s disappearance. Instead of celebrating her transformation, she finds herself spreading rose petals into her mother’s empty grave.
When Logan, her best friend from junior high, moves back to town for college, he vows to help her find the answers she so desperately seeks surrounding her mother’s disappearance. As they begin uncovering clues, it becomes apparent that the life of white magic they both grew up loving is not what the majority practices, and their lives are in danger.
With a haunting feeling that her mother may still be alive, she begins to hear a call to the wilderness. Triss realizes that in order to find the answers she needs, she must learn the ways of her ancestors and become the hunter, not the hunted before it’s too late, and she becomes part of the lonely souls. From Goodreads

A girl about to turn 18 loses her mum, not necessarily dead, but she disappears. Most of her coven friends turn out not to be as friendly or helpful as she has thought all her life. An interesting twist with a lot of dark, evil magic and of course there is romance in it as well. I liked it enough that, after finishing it, I bought the second book in the series.
