War of the Fae (Book 4, New World Order)

Will the fae be able to make the sacrifices they must to survive? ... Jayne Sparks and her Light Fae changeling friends face off in the final battle against their enemies. But the identify of their true enemies isn't as clear as it once was. Are they the ones breaking down their doors ... or perhaps another entity, hiding in the shadows? Friends come and go, bridges burned are rebuilt, love is lost and found. The survival of the fae depends on the answer to one question: Which burns hotter...hatred or hope?
