Book 3 of Your Guardian Angel: With Y/n Phantomhive now free from her Guard Dog responsibilities, it allows more time for her mind to grow curious of her family's deep past and her future with the devilishly demonic butler, Sebastian Michaelis, who is also, in his own way, free. No longer contractually bound to orders from the Couness, it leaves him open to new opportunities. The Phantom Nightclub reopening brings the Y/n and her butler back to America where secrets lie waiting; along with the club's new charming General Manager.

A modern day angel summoning goes horribly wrong when a demon shows up in his place, claiming this was all on purpose. The demon, being several centuries out of work, then takes interest in knowing you were meant for an angel, and intends on keeping you and your little black heart to himself.
