In the exciting conclusion to Herbie Brennan's New York Times bestselling Faerie Wars series, a child who is half faerie, half human has the power to determine the fate of both worlds. The Faeman Girl is Mella, daughter of Lord Henry and Queen Holly Blue, half faerie, half human and all trouble.

When Mella accidentally travels to the country of Haleklind, she discovers rebel forces preparing an invasion using magical manticores.

Old favourites are here - Brimstone, Lord Hairstreak and Pyrgus - but readers will identify immediately with Mella, whose stubborn streak and feisty daring must save the faerie realm from mass destruction.
