Winging It — Rebecca M. Senese

Eed graduates from an insect familiar to a raven familiar, but his first pairing with a pushy warlock ends in disaster. Eed barely escapes before the warlock enslaves him, breaking the rule of cooperation between witch and familiar.

But when Eed tries to return to the raven clan, he finds himself blacklisted. Facing enslavement to the warlock or getting busted back to insect, Eed turns rogue.

How can Eed clear his name before the raven clan catches up?
