Deidre's Death (#2, Rhyn Eternal)

Gabriel – Death – is winning the ground war against demons in the mortal realm. But a rebellion is brewing among his army of grim reapers in the underworld he still can’t access. Worse, just when he thinks he knows where his heart belongs, he discovers there are two Deidres: the human he started to fall in love with and the deity whose love-hate relationship with him spanned thousands of years.
