Whatever Happens by Micalea Smeltzer

Violet Page is having a rough time. This former popular girl is lost. Her parents uproot everything after her younger sister’s suicide, moving states away to escape the lingering pain of loss. She doesn’t fit in anywhere, but finds herself strangely drawn to the boy she watches view the world through a telescope.
Finnley Crawford isn’t your typical boy next door. Being autistic has always set him apart from kids his age. None of them quite knows how to approach him or interact, leaving him only one friend in the form of his support dog. His lack of friendships lead him to a unique love of space and aspirations of one day reaching the stars. For in the stars, he sees a peace and beauty he can’t find on Earth.
