Ramiel by Brenda Trim, Tami Julka

Ramiel , a newly-appointed Angel of Retribution, is out for his pound of flesh…demon flesh. When his charge Isobel is kidnapped and taken to the Underworld he is determined to get her back, no matter the cost. Even ally with a Fallen Angel, the antithesis of everything he fights for.
Their mission places them in the Inner Circles of Hell and pulls Rami to the razor’s edge of passion with Zakara. If the challenges of the Underworld don’t destroy him, succumbing to her seductive touch could be his fatal mistake.
