Ferocity

The Immortal Doc Holliday #17

by M.M. Crumley

A house divided cannot stand… Not even the house of Doc Holliday.
One foot in the waking world and one foot in the dreaming is enough to break any man, but Doc has no choice and maybe he never has. The revelation that Doc was more than he seemed long before he became immortal sends him reeling, and the world is going to pay the price unless Doc can find a way to settle his savage soul. Can Doc continue to walk the line between worlds without destroying them both and everything he holds dear in the process?

Dive into a hidden world of magic and mayhem to find out now!

Hi, I'm M.M. Crumley Your Author Extraordinaire (Also Known as M.M. Boulder)

As M.M. Crumley I write Urban Fantasy books full of supernatural action, nail-biting-mystery and; laugh-out-loud humor. Why? Because stories, myths, and legends have always been a huge part of my life... As a child, I liked nothing better than to lose myself in a world where magic and heroes were part of the fabric of existence.

As my pen name M.M. Boulder I write psychological thrillers and murder mysteries that bring the darker impulses we may not feel completely comfortable with into the light. My stories are full of lies and deaths, but there is always justice. A type of justice that's not afraid to get its hands dirty. I write morally ambiguous characters who are pushed to their limits and take matters into their own hands. In my world getting away with murder has never been so much fun!

No matter what I write every one of my characters are real to me. They exist. They are three-dimensional beings who demand that their stories be told. If I were to turn away from them, they would haunt me; and so I don't. Instead I chase after them and write down everything they say!

I have several series to help you scratch your itch for adventure:
THE HOUSE OF GRAVES Series
THE IMMORTAL DOC HOLLIDAY Series
THE LEGEND OF ANDREW RUFUS Series
JANEY FALKE: SAINT KILLER Series (Coming Soon)
Five Deliciously Dark Psychological Thriller Novels
And More...

[Melissa · Rating 5 out of 5]

Always an interesting read with the Doc Holliday series. Just when Doc seemed to be getting his life in order, an old nemesis seems to be moving back into the picture. This may be the biggest battle Doc has had to face, something to rival what Andrew Rufus went through. Just have to wait for "Onslaught" to find out.

[Elizabeth Meadows · Rating 5 out of 5]

The culmination of so many plotlines

The culmination of so many plotlines in one book makes The Immortal Doc Holiday Series my favorite tale right now. It is a captivating story for anyone looking to submerge themselves in the Immortal, Fae and Supernatural world created by M.M. Crumley. I hope you have enjoyed the previous sixteen books as well.

[Quentanna · Rating 4 out of 5]

Finally caught up and wow just binged another long series and what a journey 😭. This book was really nice breather and aftermath of the fae arc. Doc finally found his forever woman in the material realm, honestly I wasn’t expecting that. I kinda got use to him being the playboy while having Tosie in the dreaming. I guess like Doc at some point we need a change like him. Everyone is finally growing up and maturing which is nice to see since it’s been about 2 years now since book 1.

Doc is getting stronger even though it’s already been hinted and since he’s been altered he got some magic abilities too. I hope he’s come to accept it but will the fae magic alter his personality again? Anyways this was a good transition book just a nice recap to reposition some characters since we kicking off a new arc.

Well, again a spell binding page turning story. Ladies, be aware, it seems our eternal number one batchelor may have found his forever lady. Even the Baker kids like her. She can even make it so Addison can always wear her Unicorn horn. Maybe they will have a party for that. The Dream realm reveals not all foes have souls he can reach. Is Jury's dad's soul hanging around? Doc has one epic battle in this book. Ms. Cummings brings the reader into a pleasant happy journey. When that other shoe drops, you will not be able to drop the book!

[Sabrina Hayes · Rating 5 out of 5]

Fantastic!

Another fantastic story of Doc and crew! Filled with the witty banter, we all know and love this book has everything. Action, adventure, love, jealousy, and a very eclectic group of people who are indeed family. From Doc's internal struggle to find himself after this time as The Fae to finding out things aren't quite what he thought. This book is a page turner. Couldn't put it down!!

[Maria · Rating 5 out of 5]

Series continues to amaze and enthral

There just can never be enough Doc. He is an incredibly complex, flawed, yet perfect man and continues to surprise and amaze you. I love that Janey features in this book and the positives that come Doc’s way. That ending though! How are we expected to wait to find out what happens next?

[amy wailes · Rating 5 out of 5]

Always entertaining

I look forward to a new book always. The characters have a depth to them that continues to grow and change with each new story. I always look forward to the changes and continued growth of doc Holliday. The books are always an easy read and fast paced. I never know what to expect. I will keep reading until the author is done writing.

Things are getting ugly

I read this just waiting for the shoe to drop. It didnt just drop it slammed and stomped!! No one can weave a story or plot like M.M. Crumley! It was like a family reunion visiting all the people in Doc's life. What an adventure as always and that ending. P!ease bring on the next book please!!!

[Dana Delamar · Rating 4 out of 5]

Argh!!!! I need more now!!! I enjoyed this as usual and was very happy to see Doc taking some different sort of risks in this story. I feel like this one ended a little early though... but it sets up a hell of a cliffhanger!!!

[Cami Grenier · Rating 5 out of 5]

Amazing as always

M. M. Crumley is an amazing writer. I've loved all of the Doc Holliday books and Andrew's stories. I'm getting ready to start reading the Janey Falke books next, I'm expecting that they will be great too.

[Teresa · Rating 4 out of 5]

Philip is back

Doc gets a girlfriend, jury's dad's soul is missing and his other son Alex makes a attack move but unsure if he is in the driving seat?
This battle continues in next book when it's out.

[Alison Claire Humphrey · Rating 3 out of 5]

Interesting Read

Interesting read. It took a while to get to the actual plot, after a somewhat lengthy build up to it. But glad I persevered and looking forward to the next book in the series to find out the outcome of this story line.

[Ian Tomlinson · Rating 5 out of 5]

It started off a bit slow but it got back to the usual Doc Holliday pace by the end looking forward to the next one.

The book was probably fine, but the series had just lasted beyond my interest. DNF
