The Dragon in the Doghouse (FE Stories)

When five adventurous siblings - Caymen, Bear, Cash, Callen, and little Sunny - stumble upon a mysterious glowing egg deep in the whispering woods, they have no idea it's about to hatch into the adventure of a lifetime.  What bursts from the shell is Zibble, a baby dragon full of mischief, magic, and mayhem.  As the children try to care for their unexpected guest, they soon realize that even the most enchanting creatures no longer belong in the human world.  With the help of a wise sasquatch and a shimmering forest portal, they must make the hardest choice of all:  saying goodbye.
