A Waltz of Sin and Fire, book 1: The Crossing GateAsiel R. Lavie2022

In the kingdom of Elpax, juveniles must walk through the mysterious Crossing Gate to become adults—and seventeen-year-old Lenora is determined that her third attempt at crossing to adulthood will be successful. Even though adulthood means facing horrible realities, such as sin-spots appearing on her body whenever she commits a sin, it also means being able to have a job. And Lenora needs to work to support her struggling family.

But Lenora's Crossing Day goes horribly wrong.

Accused of trying to start a revolution, Lenora must obey the kingdom's laws to the letter if she wants to take suspicion off herself. But following the rules isn't as easy as it sounds. Especially when she meets a mysterious and handsome stranger who makes her feel emotions she's never experienced before—even though juveniles in Elpax aren't supposed to be capable of falling in love.

With the long arm of the law looming over her and her family, Lenora must walk a tightrope between following the rules and investigating why she's unable to cross. Not to mention discovering where her new adult emotions are coming from. But as Lenora uncovers more of Elpax's terrible secrets, she realizes that fighting the system might be the only way to save her family, her country, and her first love.
