Hellhound in a Handbag

Linked to a mage she hates, Freddy is willing to trade all the power of the demon zone to get her freedom.

Freddy was born to take the mantle of hellhound, but she wasn't fond of the idea. Wearing the responsibility to atone for the work of a homicidal ancestor, Freddy is the eleventh generation tied to the victim's family, and being bonded to a mage halfway around the world is tiring.
At a moment's notice, Freddy can be yanked from an event or her own bed and pulled across the world to act as the mage's familiar.
Her friends want to help, but there is only one way to get her out of the indentured servitude that her family has landed her in. She needs to find a stronger mage to take her on as a familiar. The hard part is finding a stable mage to link to. The weird part is watching her friends auditioning them.
