An electrifying rom com of rivalry and redemption, perfect for fans of Emily Henry and Daisy Jones and the Six, from New York Times bestselling author Emma Lord. Once the most notorious rivals in the music scene, pop princess Mackenzie Waters and punk rockstar Sam Blaze electrified audiences as their bands clashed on stage. But behind the scenes, their simmering tension grew into something more -- until suddenly both bands fell apart, and the idea of Mackenzie and Sam did, too. Two years later, Sam has traded the rockstar lifestyle for a quiet life raising the son he didn't know about. Meanwhile, Mackenzie is dealing with a postoperative change in her voice by only singing under a pseudonym. The only way to revive their public careers? A joint comeback album. With fans over the moon and their futures on the line, Sam and Mackenzie face their biggest challenge yet: giving up their old rivalry and learning to work together. But as old sparks fly and new secrets emerge, they set off a chain reaction neither of them could have anticipated -- one that proves that sometimes, the greatest hits are the ones yet to be written.
