Spark. Emerson and Sebastian

Sometimes it only takes one spark for feelings, turned to ashes, to flare up again.
Sebastian was everything to Emerson – the best friend, first love, destiny. Until one day he disappeared without explanation. It happened ten years ago when the strongest fire nearly wiped the city of Legacy off the face of the earth.

At that time, Emerson decided to stay and found the strength to move on. But Sebastian's unexpected return turned her world upside down.
He came back to revive that same elite fire brigade which was once the pride of the city.
Emerson knows: Sebastian is the flame that cannot be approached. Old feelings flare up instantly, and attraction turns into a force of nature. If she lets him back into her heart, she will burn to ashes – and this time, there will be nothing left of her, not even ashes.
