Wandering Star by Willow Hadley

Cricket Kendall has learned a lot about herself in the month leading up to her long-awaited eighteenth birthday. Not only is she more powerful than she ever imagined she’d be, she’s also discovered she’s an alpha and most likely soulmates with three hot-ass werewolves.
And now, her birthday is finally here. The day she’ll reach the full potential of her magical power as a witch, and the day she’ll finally see a mate mark on her wrist that proves she belongs with Theo, Hollis, and Cas. Everything should be perfect.
Things don’t go quite as planned, however.
Everyone seems to have been keeping secrets, one of her relationships is crumbling, and Cricket learns even more about herself than she bargained for. Cricket needs her guys by her side to support her. Whether they’re soulmates or not, Theo, Hollis, and Cas are her best friends first.
At least, she hopes they are.
