The calm, well-ordered world of Elina Serebryova collapsed in an instant: her father brought home a slightly rough-edged young man and declared that Mark was his son, meaning that Elina now had a stepbrother. From the very first minutes, their meeting went disastrously—though, really, what could happen if they’d literally saved each other’s lives?
And yet, these two made a bet.
If Elina wins—Mark will disappear from her family forever.
If Mark wins…
Elina prefers not to think about that. After all, she isn’t used to losing.
