Stars Collide by Rachel Lacey

Eden Sands has been a star for twenty years, but it’s lonely at the top. Her mediocre marriage just ended, and her inner circle is smaller than ever. The stage is the only place she’s ever felt like she truly belonged, and yet, her last album flopped, and her upcoming tour hasn’t sold out. Eden’s desperate for her star to shine bright again, but when her team suggests a collaboration with an up-and-coming young star to give her a boost, she balks.
Anna Moss is pop music’s rising star. She’s idolized Eden Sands for most of her life—so it’s a dream come true when she’s invited to perform with her at the Grammys. Anna’s tired of being defined by her bubbly persona. She wants to be taken seriously as an artist, and a duet with Eden could be just what she needs.

As Anna and Eden rehearse, they soon realize they have more in common than their musical talents. Now they just have to decide if what is between them is a one-hit wonder or the making of a romance worthy of one of the greatest love songs of all time.
