I am a big fan of the Maggie Quinn: Girl vs. Evil series because it's fast fun reading that will appeal to a wide variety of teens.
Maggie Quinn has psychic abilities, but she is still just learning how to use them. She often encounters demons and other supernatural beings and she tries to figure out how to banish them from earth. In the previous books, the demons showed up at the prom and in a sorority house. This time, they show up in a small ranch town in Texas in the form of demon chupacabras.
It's up to Maggie and her best friend Lisa-(who does wiccan-like spells) to help this town. There is a lot of action and many encounters with the demons. Also, it's a mystery in which the reader learns a lot about folk lore and the supernatural while Maggie tries to figure out what the demon is, why it's there, and how to fight it. Another great entry into this fabulous series. CLICK HERE to see all the books in the series
