The Mage And The Magpie by Austin J. Bailey
Brinley has spent most of her life lost in her own imagination, teaching bullfrogs to do gymnastics and pretending to be invisible. Now, when a magic bell from another world summons her across time and space on a journey to find her mother, she will discover real friendship, face true evil, and overcome her greatest fears in order to save the ones she loves.
An invisible girl. A missing mage. A world in need…
The Mage and the Magpie is the first book in Austin J. Bailey’s Magemother series: an epic middle-grade fantasy adventure series with witches, shapeshifters, and cliffhangers, and awesome kids (There are no boring adults in this book!).
