Keeper of the demon of Secrets Amun is possessed by demons, has been driven to near madness and has been chained and isolated to protect himself and others until he meets Haidee a fellow prisoner of the Lords and hunter who has been raised to hate the Lords but finds herself attracted to Amun and seems to be the only person able to save him. The angels who have allowed Amun to live whilst he regains his sanity demand that he returns to hell with Haidee to expel his demons but at what cost?
I really enjoyed the Amun and Haidee's story it was actually really romantic in a love conquers all kind of way. The sexual tension between the two enemies was desperately hot probably because it was built up so much and exploded pretty much at the end of the whole book. Amun who if I am honest, I never really paid much attention to in previous books, was a really lovely tortured hero- he can't speak for fear of all the secrets he knows spilling out and hurting everyone that he loves. Awwwwww.
The Darkest Secret also really brilliantly set us up for Strider's book which I have such high hopes for. I loved the scenes with Strider, William and Paris on their mini holiday with a bunch of strippers and the text messages between the Lords were hilarious. I am really hoping that after Strider we see William's book (with Gilly maybe???) I adore him!
Overall I thought it was a 4 and a half, I had kind of forgotten how good this series really is.
