Blessed Death by Amy Sumida

Sometimes Death is a blessing.
Death was once something for the Godhunter to fight, but now she knows him intimately. She knows that the Angel of Death can be beautiful, charming, and irresistible. Sometimes Death is a blessing, and at other times he can be a curse, but Azrael is always loyal and always loved. Until he resigned, that is. Then the Angelic Host was sent after him. But there is more to their actions than simple retribution. Someone is manipulating the Host, and if Vervain wants to save her husband, she must first discover the secrets of Heaven, Hell, and the heart of Death himself.
