A Life Less Beautiful by Elle Brooks

Ellis Hughes has loved the girl next door since he was ten-years-old. She was his sun, moon, and every visible star in a clear night sky. She was also his biggest regret.
When a terrible accident rips Ellis and Harlow apart, it shatters both their hearts beyond repair. More than a decade later, Ellis has paid his penance, but his regret still lingers, and the love he once harbored for his childhood sweetheart has never faded.
What Ellis believes has been destroyed forever, slowly comes back to life, only for a cruel twist of fate to intervene. Knowing he cannot live his life without Harlow in it, he faces the ultimate test of selflessness. He must sacrifice his own heart to mend hers.
