The Familiars is the first book of the book series of the same name.
"THE FAMILIARS are the magical animal companions to a wizard or witch. When three young wizards-in-training get kidnapped by the evil queen of the land, it is up to their familiars to go a dangerous journey to rescue them. You'll meet Aldwyn, an orphan alley cat pretending to have telekinesis; Skylar, a know-it-all blue jay who can cast illusions; and Gilbert, a hapless tree frog with the ability to see visions of the future in pools of water. See what happens when these three animal assistants -- typically relegated to the background or found sitting quietly on their wizard's shoulders -- go on a heroic adventure of their own!"
