October Darlings (Wretched Darlings #1) by Wendolyn Baird:
 
Something is haunting Adeline Nix, and it's more than even a houseful of spirits can take on. Most seventeen year olds expect a cake on their birthday, but Addie's birthday is approaching with a completely different type of gift. Learning she's a clairvoyant is one thing to process, but when metal scorpions come to life and an unfamiliar entity makes itself known, she knows there's something much more powerful at work. Graveyards can be sanctuaries, solitude can be deadly, and some deaths are too tragic to recall. It's up to Addie to find the balance between past and present before it's too late.
