The change is full of fresh possibilities, but it's also a tiny bit scary. It gets scarier when a minotaur walks in the door. And even more shocking when a girl who looks just like her shows up to fight the monster.Gretchen is tired of monsters pulling her out into the wee hours, but what can she do? Sending the minotaur back to his bleak home is just another notch on her combat belt. She never expected to run into this girl who could be her double, though.Greer has her life pretty well put together, thank you very much. But that all tilts sideways when two girls who look eerily like her appear on her doorstep and claim they're triplets, supernatural descendants of some hideous creature from Greek myth, destined to spend their lives hunting monsters. . . .

But when the girl appears at Isola's window, her every word a threat, Isola needs help.Her real-life friends – Grape, James and new boy Edgar – make her forget for a while. And her brother-princes – the mermaids, faeries and magical creatures seemingly lifted from the pages of the French fairytales Isola idolises – will protect her with all the fierce love they possess.It may not be enough.Isola needs to uncover the truth behind the dead girl's demise and appease her enraged spirit, before the ghost steals Isola's last breath.
