Heart of Stone by JM Paquette

Between rockstars and fae Lords, what’s a girl to do?

Margot Tanner has had a crush on Ash Stonewall since she was 15. Though close with her cousin Niklaus Hodges and drummer Timothy Green, the elusive Ash has always been just a step out of reach. Years later, Margot is the stage manager for the band Stone Dragons as they tour the country, but she is tired of longing for the unattainable Ash. With the gentle encouragement of Nik and Tim, she attends an afterparty and meets the mysterious Tobin Fetch. Their instant connection is a surprise, but even more shocking are the fairy wings that suddenly erupt from her back after exchanging a few kisses in a dark room.
Ash Stonewall has enjoyed hiding among the humans, following his father’s decree to stay out of fae politics. However, the temptation of Margot Tanner has always been troublesome, and he dreads the day someone discovers Margot’s untapped potential. Now that Tobin has unlocked her true identity, Ash has to decide what is more important: hiding his true nature as a fae Lord and maintaining his rock star identity or revealing himself and claiming Margot as his own to protect her from fae who would abuse her gifts.
Tobin Fetch always has a plan, but he never expected to stumble across an Unclaimed fae at an afterparty. Never one to ignore such a boon, Tobin is quick to free her powers, launching her into the fae world, but he never expected to want her for his own. Bound by loyalties in every direction, Tobin must decide how far he is willing to go to protect this newfound treasure.
Caught in the middle of forces she barely understands, not to mention a band tour that seems to attract more and more frenzied fans, Margot must find her place in a world where everyone answers to someone. In this strange hierarchy, where does Margot belong?
