Wolf Call: ICRA Munich (Books 4-5): A Werewolf Urban Fantasy Suspense Romance Paperback – February 20, 2024
Purchase options and add-ons
Dirty players require a dirty game. And I have to be ready to play the filthiest one of them all.
First, I fall into my own personal nightmare when I’m sent to Berlin to track down a serial killer who’s too close to my fucking heart for my own good.
Then I get slapped with a reality check of a different, though no less concerning kind.
The crime net I’ve been bleeding to dismantle is more elusive and resilient than ever. More dangerous, too.
If I want to catch the top players, I need to adapt my game.
But blowing off our old tactic comes with a serious gamble.
Yes, I might win and burn the vile organization to the ground.
But if I fail…
The case isn’t the only thing I’ll end up losing.
Fans of Keri Arthur, Patricia Briggs, and Diana Rowland will love the final two books in the explosive, scorching hot Wolf Call: ICRA Munich series where supernatural forces clash in a cloak-and-dagger war!
Boxed set includes: Phantom Moon (Wolf Call: ICRA Munich #4) and Burning Moon (Wolf Call: ICRA Munich #5)

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 2, 2023Wow! These last 2 books in Lotte's story really pack a lot of action and twists into them! When I first met Lotte in the ICRA Berlin files I didn't like her as well as Gina. Plus, I'm not a fan of tennis so I didn't jump into reading the ICRA Munich books until later. I enjoyed the first 3 but these last 2 are by far the best. With Lotte gaining new abilities and now learning to use them, Raya still pursuing her, her mate bond still not claimed, and the new murders pointing towards someone dear to her heart, Lotte has a lot going on. All of the subterfuge in the ICRA is mind boggling as everything rushes towards the climatic ending. Author Kos has outdone herself!.

- Reviewed in the United States on February 1, 2023Phantom Moon (Lotte Freundenberger #4)
“Don’t try to deny what you feel, even if it doesn’t make sense to you at the moment.”
Lotte didn't set out to become an ICRA agent, but now that she is one she's going to do the job as only she can, with determination, the help of trusted friends... and on her own terms.
One of the greatest strengths of this series is that it not only remembers past events, but Lotte faces the consequences of past actions and has to deal with the repercussions of past choices and missions.
In every way possible she is growing and evolving, as an agent, as an adult with her personal relationships, and as a supernatural being.
Burning Moon (Lotte Freundenberger #5)
"...my demonic sigil was damn cute."
Lotte is working a big case, which unfortunately brings back traces of the initial case that brought her and ICRA together.
This is the book where pieces from across the four previous books come together, and the impressive community in this story truly shines.
Lotte is a were who was experimented on, against her will, resulting in her continuing to evolve, and learn about herself... and as she accepts herself she is also learning more about those who are like this new part of her... the good, the bad, and the misconceptions.

- Reviewed in the United States on January 30, 2023Set two of this fantastic series contains books Phantom Moon and Burning moon and once again this draws you into its fantastic world. Lotte returns and once again her world is full of danger, action, drama and suspense as she hunts down the baddies to save the day. Twists and turns are thrown our way and not all of them are good and we see old friends and make some new ones as we follow Lotte and co battle to take down this organisation once and for all.
- Reviewed in the United States on February 3, 2023Lotte returns with her team to solve a series of killings, while trying to deal with her own personal challenges. Not everything is what it seems, betrayal is everywhere, emotions are on the line, drama and suspense at the fore front. We have the return of old acquaintances, the beginning of new ones and a whole lot of twists.

- Reviewed in the United States on January 17, 2023Lotte lives very much on the edge: so close between life and death, demons and disarray, disaster and love and friendships forged and mended - or broken entirely
which alliances are built for betrayals and destruction? for protection? at what costs?
life and deaths that are more than survival- or not.

- Reviewed in the United States on February 17, 2023This book was filled with betrayal and sorrow. I even cried at one point and was happy at the next. A very emotional read. I would recommend reading this book.

- Reviewed in the United States on January 22, 2023This is a box set of books 4-5 of the ICRA Munich books. The books are set in the “future” portion of the Kolovrat Universe (in which the Black Werewolves and Nightwarith Series are set) at around the same time as the Shade Assassin books. Chronologically, I think the Shade Assassin set occurs after these books as these characters are mentioned in those books.
I had enjoyed the Shade Assassin and so looked forward to these but was unfortunately underwhelmed by the first 3 books and so had to force myself to read these. These were okay books. I had the same issues as with the first 3. The romance was sadly lacking. I couldn't really relate to the main character and honestly I don't know why the h and H fell for each other. The story and suspense was meh at best. There was no backstory on the Fruenbergers (and so I didn't understand why Lotte did what she did and why she was so opposed to being one), Lotte’s ability to solve these mysteries wasn’t convincing. She would be bumbling along and suddenly would “get it” and voila.
Overall, I didn't feel that these were as good as her Shade Assassin series and I think I expected more. An okay read.

- Reviewed in the United States on February 8, 2023Lotte is the type of character that will have me coming back for more. She’s amazing to read and no matter how messy and rough her life gets she gives it 100%. This has awesomely twists and turns and will keep you up all night easily.
