Transient Moon: A Werewolf Urban Fantasy Suspense Romance (Wolf Call: ICRA Munich) Paperback – February 5, 2024
Purchase options and add-ons
Three months. I’d spent three months cooped up at the ICRA facility, probed and prodded for any genetic changes my hellish experience in the supernatural labs might have left me with.
Now that I can basically taste my freedom, all I desire is to return to the Zentrum. To Afanasiy. My friends.
Definitely not entangle myself deeper with the Agency, even if Isa is convinced I’d thrive among their ranks.
I’m able to blot her out—until a brutal assault leaves my former lover on the verge of death.
I want to do my part. Burn to get justice for Melina.
But getting involved in the case means striking an unbreakable deal with Isa.
And if I do…
I might as well raze any semblance of my former life to the ground.
TRANSIENT MOON is the third book in the Wolf Call: ICRA Munich series, perfect for fans of Chloe Neill, Diana Rowland, and Keri Arthur who love complex heroines, scorching hot demon romance, and urban fantasy with a touch of darkness to it!

Editorial Reviews
From the Inside Flap
Each series (or standalone title) is its own complete work within the Kolovrat universe. You don't need to have any prior knowledge, simply dive into what feels best to you at the moment.
However, if you want to see the larger picture and enjoy the many crossovers peppered throughout my works, I do recommend eventually picking up all the available titles.

- Reviewed in the United States on February 26, 2019Overall rating: 4.7
This book is packed with everything a reader like myself is looking for and then some. Not the first book with these characters yet this could be read as a stand-alone. Fair warning, you will want to read the others after reading even one, for these characters are so worth their whole stories! The storyline itself is full of fast paced action, deep moral dilemmas, questionable love interests, suspenseful plot twists, and definitely mature content not for innocent eyes. A mystery is definitely resolved in this tale, but even deeper secrets have been uncovered and will leave you wondering! Stunning! All my reviews are always voluntarily written.
- Reviewed in the United States on February 26, 2019time and again Lotte is willing to risk or sacrifice herself for those she cares for - friends, blood family, love family.
time and again, she also deals with the consequences of betrayal - someone else choosing to keep true to someone or some thing other than her.
the internal bond she has to her Demon Ifanasyi might well be more torture than comfort in its own way, but it may well also be unexpected protection.
Lena her Nightwraith friend may find some release, and fight hard for her, just as their physician friend suffers at the mania of a deranged admirer.
More than one in her circle will choose loyalty to different means and ends than Lotte does - and it will cause her many types of pain.
A new phase starts in life for Lotte, but really not the one I was expecting for the werewolf.
A bumpy, steamy ride just took a sharp turn - again. I am eager to see the new directions and destinations she will now meet.

- Reviewed in the United States on July 20, 2020Format: KindleGaja J. Kos brings it and then some in the third outing in the “Lotte Freudenberger” series Transient Moon. We pick up the day before Lotte’s quarantine ends, approximately three months after Darkening ended. Lotte has been tested physically, mentally, and genetically. She is ready to be let out and get back to her own life.
Unfortunately everyone has plans for Lotte, especially with a drastic turn of events. Melina is beaten and is in a coma. Isa offers her a chance to find Melina’s assailant, but at a steep price. Another player enters the field and makes an offer to Lotte too.
Old friends come in for an assist and introduce Lotte to some new friends - who I want to see a lot more of! Lotte makes choices and watches others make choices that for Lotte they cannot come back from.
Transient is not so much an action story this time around as it is an emotional rollercoaster for Lotte. Decisions are made, then have to be unmade. This is a hard time in Lotte’s life and I do not envy her. Kos puts Lotte through her emotional paces and we all suffer for her.
This is the perfect title for the book as Lotte is in a period of transition. Kos packs this story with surprises, betrayals, new allies, and unexpected consequences. Pour yourself a huge pot of tea because this is a book you will want to talk about after reading.
I received an ARC of this book and I am writing a review without prejudice and voluntarily.
- Reviewed in the United States on April 10, 2019Our heroine has just gained her freedom, but will she sacrifice it for friendship?
This is a paranormal story with a mystery at its core. This is also not the first book in the series, but it can easily be read out of order. The reader will be able to pick up the important details pretty quickly. Of course, you will probably want to go back and fill in the gaps after reading this one.
The story is solid, with a good strong plot and well developed characters that draw you into the story. There are several twists and turns along the way which will keep the reader guessing and engaged in the story. I quite enjoyed it and found it hard to put down before finishing.
Highly recommended.

- Reviewed in the United States on February 26, 2019Lotte has been through so much and her troubles aren't over yet. It seems fate is not done with asking her to be willing to make the ultimate sacrifice or with bringing people into her life who are going to betray her trust and cause her immeasurable pain. A fantastic addition to the series with characters to vibrant they leap off the page and a story that is well-written, complex and captivating.

- Reviewed in the United States on March 2, 2019I have ever been a fan of this author since the release of her Nightwraith series. Action packed and well written, this story moves along as Lotte returns to her beloved tennis club, her loyal friends and business partners and her demon lover Afanasiy. But the brutal beating of her former lover has her out tracking the attacker and puts her up against some nasty fiends. I loved reading this book but the ending was so sad.

- Reviewed in the United States on February 26, 2019Lotte is back and facing even more difficult choices as she finally touches the freedom she has been waiting for. This was a great, action packed book with well-developed characters that keep you thoroughly engaged. I’ve been enjoying Lotte’s story and can’t wait for more.
Transient Moon is the third book in the Lotte Freundenberger series.
