From Case Closed author Lauren Magaziner and award-winning artist Mirelle Ortega comes the first book in a new highly illustrated middle grade fantasy series. Full of action, adventure, and friendship, a team of five girls must stop a powerful villain by finding their mythical familiars.

It's Pairing Day in Terrafamiliar! Marina has been waiting for this moment—anxiously—for as long as she can remember. Because today's the day she gets to bond with her animal familiar for life, like every other ten-year-old in the land.

Except after the ceremony ends, Marina doesn't have one. And she's not alone . . . four other girls also didn't get their animal companions. The leaders of Terrafamiliar realize something special is happening: Marina and the other four girls—Kit, Ember, Pippa, and Hailey—are called Mythics

In times of unrest, the Mythics must earn their Mythies—mythical beasts—in quests of courage. But danger lurks everywhere as there are others seeking this mysterious power. And only the Mythics can save Terrafamiliar!
