The Monster Realm — Nara Duffie

Medusa aimed her poisoned arrow right at Lillian ...

Lillian always loved stories about myths and monsters--until she found herself inside one, fighting for her life!

Joined by her best friends, Katy and Maisy, Lillian must cross a sea guarded by Krakens and sirens, race through a dark forest haunted by elves and chimeras, and cross mountains ruled by griffins and rocs.

Where in this world is Lillian's sister? Who is the mysterious boy with the stone medallion? Why do the monsters hold an ancient grudge against humanity? And what is the secret hiding at the heart of it all?
