Guardian trainee Violet Fairdale is just weeks away from one of the most important occasions of her life: graduation. After messing up big time by bringing a human into the fae realm, Vi needs to step up her game and forget about Nate if she hopes to graduate as the top guardian of her year.

Protecting humans from dangerous magical creatures is all in a day's work for a faerie training to be a guardian. Seventeen-year-old Violet Fairdale knows this better than anyone - she's about to become the best guardian the Guild has seen in years. That is until a cute human boy who can somehow see through her faerie glamour follows her into the fae realm. Now she's broken Guild Law, a crime that could lead to her expulsion.

Having escaped an Unseelie prince and a world of shadows, Emerson and Calla are now hunted by the Guild of Guardians. On the run, constantly trying to remain one step ahead, they must figure out how to find and rescue everyone the Guild has taken from them. Then, in an unprecedented move, Unseelie Prince Roarke breaks the fae realm's most important rule. Now two worlds stand on the brink of war. Caught in the middle between guardians and Prince Roarke's forces, Em knows her Griffin Ability is powerful enough to stop them both.

Thrown into an entirely new world of faeries, enchantments - and the annoying guy from down the road who, it turns out, isn't human either - Em barely has time to learn even the most basic of magic before another startling truth reveals itself: she has a Griffin Ability. A special kind of magic feared by most fae. Now she's at the top of everyone's most-wanted list - including the mysterious glass faerie carrying out random attacks on fae.

Emerson Clarke thought magic might solve all her problems. Turns out, magic only made her life more complicated. Her sick mother is in a worse position than before, and Em just made a risky deal with an Unseelie prince: he will heal her mother if Em agrees to the ultimate alliance - marriage. With the possibility of finally getting the one thing she's always wanted, Em enters the dangerous world of the Unseelie Court. She'll learn whatever she has to about magic and etiquette in order to fake her way through palace life until Prince Roarke fulfills his side of the bargain.
