Large tours around the world. Over one hundred million albums sold. A whole army of fans. For Viper and the guys from TBV, the most popular rock band in the world, every day is a holiday. But one day the lead singer of the group, leaving the studio, never returns to it, and the holiday ends abruptly. Vocalists with shrill, brain-exploding voices. Distorted, clumsy songs. Fame hunters. After months of dull and joyless auditions, Viper, the lead guitarist and also the most reckless bad boy of the group, is ready to seek solace at the bottom of the bottle. Time is running out and the need to find a new vocalist is felt more and more acutely. But it seems that the group's prayers are finally answered, because one fine day an angel appears on the threshold of the studio. Charismatic. Talented. With a microphone in his hand, he simply works wonders. It was Heilo that the group had been looking for for so long. His magnificent voice matched his stunning appearance. And, of course, Viper immediately pays attention to Heilo. But this can hardly be considered a good idea, because: 1. this kind of relationship is not welcome in the group; 2. Viper has already broken rule No. 1... (which, by the way, was a very big mistake);3. Heilo is a natural. No matter how hard Viper tries, his body does not want to obey his head, at least the one on his shoulders. But the feeling of mutual sympathy is difficult to fake, both on stage and, even more so, off it. What about Viper and Heilo? And between them there is plenty of this attraction, even in excess. And while both men try to resist the growing attraction between them, the group embarks on a difficult path of rebirth and return to the top. The creation that has risen from the ashes is more beautiful, better than it was before. And when Heilo finally spreads his wings, the world understands what it means to love an angel. IMPORTANT: The "Fallen Angel" series consists of several books: "Heilo" - the 1st book, "Viper" - the 2nd, "Angel" - 3rd. All of them are about the same heroes (Heilo and Viper) + a short story about the members of the "TBD" group. The authors announced that they are writing a continuation of the “Fallen Angel” series and plan to tell Killian’s story in the 4th book. The series is still being written!
