Luna Oliver's dream of becoming a surgeon appears within reach when she secures her top residency choice in New York City. The bonus-her older brother Forest and his childhood best friend, Keegan, are physicians there. As Luna navigates the intricate world of medicine, a parallel journey unfolds within her heart. After not seeing Keegan for many years, a question continues to arise now that they're in the same city. Has Keegan always been this gorgeous, or is it a new thing? The gravitational pull between Luna and Keegan transcends the skyscrapers that surround them. But the overbearing and overprotective older brother Forest has always made it known-Keegan is like family and wholly off limits. In the city that never sleeps, Luna's heart is awakened to new possibilities, and she must find the courage to chart her own course. Luna has to decide if moving forward with her feelings is worth blowing up her entire world.
