All's Hell That Ends Well (Infernal Covenant Book 4)

by Nadine Mutas

About this book

Being a newly minted demon with some shiny black wings of my own should be a dream come true. I mean, I’m back in Hell, I’ve got power, I’m not a lowly human anymore, this could be the start to happily ever after with my boo Azazel!

If only it weren’t for that little snag…that Lucifer claimed me for himself.

Not in that way, ew, get your mind out of the gutter!

More like he directly conscripted me into his service, and there’s nothing anyone, including Azazel, can do about it.

Though he sure tries.

As it turns out, Lucifer orders me to go on a special mission for him, one that might reunite him with…you know who. Or so he believes.

I have my doubts. Just as I have some serious concerns about the state of Lucifer’s rule in Hell. Major late-Roman-empire vibes here.

And as much as I despise that mothertrucker of a devil, my health and safety are now tied to his power, and if his rule fails…

Yeah, it’s not looking good.

I never thought I’d one day fight on the side of Lucifer, but I just might have to–unless I can find her first.

All’s Hell That Ends Well is the conclusion to the Infernal Covenant series. This book is the end of Zoe and Azazel’s story and will deliver that sweet, absolutely deserved happy ever after for both of them!

The connection between the characters is unbelievable and the transformation of some of the relationships during the story just draw you in more. Its not just a Great romance!!! There is just so much more. I really enjoyed all 4 books and then went looking for more by Nadine and was surprised there weren't more out there. I will be watching for more. )

Happily ever after

That finally story was everything, spoiler alert Never thought you have me rooting for Lucifer in this story to have a happy ending. The world and characters you created truly suck a reader in and bring that character to life. Greatly enjoyed this series. )

Really good!

I definitely enjoyed this series. I think the author writes beautifully and quite well. My only complaint would be that it went a bit long for me. Sorry! I think it should have been a trilogy but I understand she felt strongly that she needed the fourth book. I found myself skipping ahead to just the dialogue at times. Still I would definitely recommend this series! You’ll enjoy Zoe, she’s adorably funny! )

Hellishly Enchanting!

I loved this whole series; Nadine Mutas has now become one of my new favorite authors! In this series she's created a complex world that gives a detailed view of what life is like both in Hell and in Heaven, which I thought was so interesting. In addition to that, she has created characters that you grow attached to and who take a little piece of your heart. And if you're like me and love a novel where romance is front and center, then you're gonna love this one! Somehow a love story with a...

Zoe and Azazel get there HEA!

Omg this book has all the feelings you'd want in the last book in this series I loved every page. It's amazing to see Zoe go from human, to angel to demon and how she pulls it off with grace her relationship with Azazel is epic she also forms a friendship with Lucifer which was great to see she still has Lilith's essence in her so her job is to find her incarnation! There is drama in this book, as well sadness so grab some tissues don't want to say a lot of what happens there are some...
