[Siren Everlasting Classic ManLove: Erotic Alternative Paranormal Romance, M/M, shape-shifters, witches, HEA] Hisoka Henderson is falling more in love with his caster every day. Being Ciel's familiar comes with a lot of perks, including being able to shape shift into a huge black panther. Between starting their new business and figuring out all the cool things his powers can do, he thinks he has it made. That is, until someone binds Ciel's powers and a summons to the Circle's headquarters threatens to tear apart their fledgling relationship. Turning to his father for help was the last thing that Ciel wanted when he quit his job a few months previously. However, he has little choice without powers. Turning to a dangerous mage may be the only way he survives, but he can’t say yet if the price is worth the cure. Will they be able to figure out the source of the threat in time or will they find their relationship implode before they get a chance to enjoy happily ever after?
