What happens when a Rock Star in Disguise meets a Billionaire in hiding? Georgie doesn’t know who she is dating. At a high society wedding, Georgie Johnson is introduced to Alexandre de Valentinois, a hereditary duke of nothing who flies around the world on his private planes and describes himself as “one of those despicable, idle rich men.” Yet, when pressed, he sings at the wedding in a gorgeous, clear tenor that tugs at Georgie’s soul, and miraculously, he calms her paralyzing stage fright so she can accompany him on the piano, even though she thought she had left her classical music career behind when she went into hiding. But Alexandre has a dark side. His name is Xan Valentine, and he’s the rock star front man for Killer Valentine. He’s famous, but his paparazzi-dogged lifestyle might get Georgie killed.

The music calls Georgie. Every night, she stands offstage, watching Xan Valentine set fire to the crowd with music until they would burn down the city for him. His music wraps her until her fingers dance, desperately wanting the piano, but her terrified legs could never walk onto a stage. Most nights, when Xan Valentine strides off the stage, his dark eyes shift, blurring, and he becomes Alexandre de Valentinois again. Sometimes, Xan won’t let go. Some of the other band members, Rade and Grayson, are caught in a death spiral of booze, drugs, and groupies. The drummer, Tryp, is too infatuated with his new wife to do more than show up to play. Xan is the only one who can compel them onto the stage. He’s holding Killer Valentine together with the force of his will. This can’t go on. Something has to break.

Xan Valentine, the rock star that Rolling Stone called “sex incarnate,” stands in the spotlight every night and sings love songs to the women in the audience. They swoon. They scream. They believe him. Georgie doesn't. They didn't see him nearly beat two men to death until someone pulled him off. They’ve never seen the coldness in his dark eyes while he sat across a table, negotiating a contract that broke their hearts. He’s never stolen into their bedroom at night, slid into their bed, and made love to them until dawn, and he’s never treated them like it never happened while the bitemarks on their backs and thighs were still sore. They’ve never seen him play the violin like an angel. Or a demon. Georgie is officially in his band now, playing the keyboards, and every concert drives the music deeper into her soul. If Georgie leaves the protection of the band and Xan Valentine, the Russian mafia will kidnap and kill her. If she stays and plays in his band for just a few more weeks, Xan will pay for her college and law school. If her heart can survive even one more night with him.

Georgie broke up with Xan Valentine, the lead singer for the rock band Killer Valentine, the guy that Rolling Stone calls “sex incarnate.” The magazine isn’t wrong, but they don’t know the half of it. He’s the alpha-est male who ever walked onto a stage or into a bedroom and might be crazy, and Georgie is definitely in love with him. Plus, he hired her ex-boyfriend, her first “real” boyfriend, to play in the band, and now she’s stuck between them. So she tried to leave. That’s what any sane girl would do. And just as she feared, the Russian mafia kidnapped her. She prays that Xan won’t try to rescue her because they said they’ll kill him. But she knows he will, even if it costs him everything. The nail-biting conclusion to the Billionaires in Disguise: Georgie and Xan series, Nothing Else Matters explores the depths of the heart and the healing power of love.
