Ali Hazelwood promises “the cello scene in this book will change your life” in this Reylo-inspired grumpy-sunshine romance full of sharp banter, deep emotion, and irresistible humor.     When professional—and self-taught—violinist Gwen Jackson plays, she disappears into the peaks and valleys of each song, a quiet passion that never quite explodes into pure emotion. Xander Thorne is the exact opposite. A cellist and a rock star, he’s all about big emotion, but not even his six-foot-four frame can contain his skill, his genius . . . and an attitude that borders on jerkitude. . Not only did it take Xander a year to notice that he and Gwen both play in the Manhattan Pops, but he also always seems to have the perfect cutting criticism about her technique. When Gwen is offered the role of first chair of the orchestra, something Xander has secretly coveted for years, their existing hostility goes up a notch. Yet, despite her best efforts, Gwen can’t ignore the sizzling chemistry between them.             Forced to work more closely with each other, they can’t help exploring their attraction. As they begin to compose and play songs together, it’s clear that their powerful connection could make for a performance that would blow everyone’s minds. Suddenly, they’re box office dynamite, and the fragile romance growing between them is in danger of being crushed beneath a publicity stunt.
