Deidre's Death (#2, Rhyn Eternal). Rhyn Eternal, #2

Two women caught in a struggle between Death and the Dark One .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 hundreds of thousands of years.
What he doesn't know: the two Deidres made a deal that will send one of their souls to the underworld by the end of the week. Deity-Deidre expects nothing but smooth sailing in her future. Until the Dark One strips her powers on her way out of Hell, leaving her a vulnerable human, reeling under the influence of human emotions, which deities do not possess. The deal she made with human-Deidre suddenly seems impossible to win.
For the first time in her existence, she understands what Gabriel felt at her mercy for the eons they were together. She doesn't know how to win the trust of the man she's always loved - or even if she can.
