Soul Rescue, Volume 2 Book

As Renji and Kaito continue to make their rounds on Earth, they arrive on an island where they happen upon the princess Shalala, who has found herself caught in an amorous arrangement--she has been made the island king's fiancé because of the superstitious lore that says they must be wed! Shalala goes into hiding, and confides in Renji that everyone must find that special someone to love--which Kaito reminds Renji is forbidden for angels to do. But how can something feel so right...and be so wrong?!
