The Faerie Guardian

Seventeen-year-old Violet Fairdale is close to becoming the best guardian the Guild has trained in years — until a human boy, Nate, somehow sees through her faerie glamour and follows her into the fae realm. Returning him home and making him forget is standard Guild procedure. It doesn't stay simple: evil faeries, a long-lost family connection, and Violet's former best friend turned rival, Ryn, all complicate the situation, and Nate turns out to be more than the ordinary human he first appeared to be. Violet ends up fighting for both their lives as the two are pulled into the darker side of her world.

The first book in the Creepy Hollow series, this is a fast-paced YA fantasy built around fae mythology, guardian training, and a central love triangle.
