Jagged Burn. Kidds Beach Fire Department, #2

Scars don't always show on the surface. Stefan Grey was once the life of the party, the firefighter with a smile that could light up a room. But after the flames took half his face and left him broken inside, he hides behind the shadows, convinced he's too jagged to be worthy of love. Until the night Anna Alexander comes crashing back into his life. Anna thought she'd escaped her small town and found her happily ever after.
Instead, she walked straight into a nightmare. Bruised, battered, and running from an abusive relationship, she turns to the only people she trusts ... her brother and the scarred man who has haunted her heart for years. Stefan wants to keep his distance. She's his best friend's little sister. She deserves someone whole. But the fire between them refuses to be contained, burning hotter with every stolen glance and every forbidden touch.
When Anna's past refuses to let her go, Stefan will stop at nothing to protect her, even if it means risking the only family he has left, and the fragile heart he swore he'd never give away again. Some loves don't heal the scars. They make you brave enough to wear them.
