The Romance of Lena Sokol. A Set of 2 Books Bad Girl + Bad Girl. The Path to You

A set of 2 books:
"Bad Girl"
Mariana is a good girl and a diligent student. Her life is a perfectly thought-out plan where everything is predictable.
Kai is a volcano of passions: sinful, bold, dangerous. Mariana's half-brother is used to carving his... way through and always acting according to the situation.
These two would never have met, but now his hatred can destroy her world, and her love can leave scars on his heart.
Love cannot forgive everything, but it can turn everyone's life upside down.

"Bad Girl. The Path to You"
The betrayal of the closest person has shattered Mariana's life to the core. Resentment, pain, anger — this is what her world is filled with. Yet her heart is torn with desires: to return to Kai, to forgive all grievances and be happy again, or to save herself while remaining alone. But how to escape from a guy who has become your entire universe, especially if he still lives in your house?
Kai is ready to get Mariana back at any cost, even to fight his inner demons. But he can only do this by letting the girl go…
Will they be able to start a new life separately, or will love overcome all obstacles?
