Succubi Are Forever (The Succubus Diaries Book 4)

Tasked by the Archangel Gabriel, Jackie Brighton must find two more lost archangel halos before she's free of her deal. But she's not the only one hunting for the immense power the halos bring, and everyone around her has motives - succubi, serim, and vampire. It's a race to the finish line, and only one person is going to come out on top.
But will Jackie stand tall when even her allies are set to betray her? Noah Gideon is back, and he's never liked taking 'no' for an answer. The mysterious assassin Sophie is helping out, but Sophie has her own agenda. So does Jackie's newest rival, the ancient hetaera Phryne, who wants to use the halos to give a new world to succubi everywhere - one that doesn't involve their masters.
Every immortal wants those halos, but Jackie's not sure they're worth her life, or Zane's freedom.
But she might not have a choice...
