Reptile

by Alex Umbra

Five bodies.

Five “accidental drownings.”

One journalist who stops believing in coincidence.

When Warsaw’s Vistula River starts giving up its dead, investigative reporter Adam Bryl notices a pattern everyone else prefers to each victim visited the same elite underground club before they died. A place where secrets cost more than blood—and someone decides who gets to walk out alive.

As Adam digs deeper, he collides with Helen, a brilliant dominatrix with too many clients in high places and too many reasons to lie. Attraction sparks, trust shatters, and the truth coils around them like a predator waiting to strike.

Because beneath Warsaw’s neon glare, a new breed of monster is rising.

And it already has Adam’s name on its tongue.

A razor-sharp thriller infused with dark sensuality, urban horror, and relentless tension.

Got it during free book promotion :D Reptile grabbed my attention from the very first chapter! Bold scenes, fast-paced action - this isn’t just erotica; it’s an intense thriller with real drive. I loved Helen’s emotional turmoil, and until the very end I wasn’t sure if the truth would come out - and if it did, how Adam, the “truth above all” type, would react. And that ending completely took me by surprise! Highly recommend!

As a big fan of 50 shades I couldn’t ignore this one when I saw “BDSM club” in this book description. Well, it is rather a few shades of Helen, but still worth reading. Good plot, hidden secrets, twist, good pace, erotic vibe - 5 stars!

Reptile is a gripping, dark, and sensual thriller that keeps you hooked from the first page. Bold, fast-paced, and full of twists — I couldn’t put it down. The ending completely caught me off guard. Highly recommend!

Reptile hit me way harder than I expected. I picked it up thinking I’d get a gritty crime thriller, and sure—there’s plenty of that—but this book goes somewhere much darker and far more interesting. I can only recommend

I enjoyed it, would be easier to follow all the characters if not the Polish names ;)

Good crime thriller with strong erotic vibe

[Adam Wagner · Rating 5 out of 5]

This was a really good crime-erotic-thriller, though not more erotic than a typical Masterton book. Quite cinematic I’d say, good plot

This one was recommended to me by a friend so even though I rarely read books from indie authors, I gave it a try. No regrets :) light style, good pace, intense - really good thriller.

[Pola Krejza · Rating 4 out of 5]

Fajna książka, dobry wątek kryminalny, erotyka po mocnym początku i środku pod koniec zanika, ale książka warta polecenia
