I'm currently reading Magicless in Nevermore by Violet Merriweather. This book is the first in the Witches of Nevermore series.
Nevermore is a world of magic and witchcraft, protected from mortals, and the home of Cassandra Holly and her family. Cassie is getting desperate. She's almost 21 and has yet to come into her magic powers. Without magic she'll be forced to leave her friends and family and the town of Nevermore itself. Desperate times call for desperate measures and with the help of her best friend Willow, Cassie tries her hand at a major spell to find her magic. Forces combine and the unexpected happens. While Cassie finds her magic, she can't quite figure out what it is. Not only that, Willow's aunt, a not quite willing aspect of the spell, is found dead-and her not quite dead spirit demands that Cassie finds out who killed her! Cassie has to deal with her new found powers, a cantankerous ghost, her family, and mean girls. Will Cassie make sense of it all before Nevermore itself is destroyed?
