Alexa spent years believing Nik was her half-brother, even after he tried making a move on her. When she visits for Russian Orthodox Christmas and finds out the truth, their relationship becomes wild and hot. Soon Alexa’s on the verge of committing the ultimate sin—falling in love with her stepbrother.

Nik’s devil-may-care attitude drives Alexa crazy but because he’s her younger half-brother, she has to see him every Russian Orthodox Christmas—even after he kissed her two years ago. This year, the holiday starts with Alexa finding out Nik’s not related to her at all, a fact her family has kept from her for decades.

The revelation sends Alexa into a tailspin and the person who offers her comfort is the last one she expects: Nik. After waking up to find Nik in her bed the next day, that comfort turns into unexpectedly hot sex, which only complicates the burgeoning feelings she has for him.

The last thing Alexa wants is to disrupt her life with a man she can’t trust—a man she already knows she cares far too deeply for. But easygoing Nik proves to be far more determined than she’d ever imagined when their fragile new love is on the line.
