All Things Rise by Missouri Vaun

Cole rescues Ava, a pilot from the Cloud City of Easton who crash-lands near her farm, setting in motion events that will alter the course of her life. It’s a hundred years after peak oil and the rich have risen above the Earth, inhabiting great Cloud Cities, while those left behind live a rural existence, off the grid. After suffering a vicious attack, Cole is transported to the Cloud City of Easton for emergency surgery. While recuperating and adrift in the unfamiliar social landscape of Easton, Cole begins a journey of discovery. When she meets Audrey, a beautiful doctor, the attraction they share is penetrating and possibly life altering. Explosions, staged by a ruthless underground movement, nearly bring Easton to the brink of collapse. The crisis that rocks the city forces Cole and Audrey to weigh what truly holds meaning and what each is willing to sacrifice for love.
