No More Hiding, Heir of the Sun

Silas, the God of the Underworld, brings an army against the Saul clan and demands they hand over the authority of the Sun God. He also demands Princess Elena, who has pure divine blood, as his wife by force. Logan has been hiding for sixteen years. He carries the purest bloodline of the original Sun God, and releasing that blood before he turns eighteen would kill him, so he has passed himself off as a good-for-nothing with no divine lineage. His stepmother Camilla, his half-brother Christian and Henrik, the clan's chief divine guard, have abused him for years on that basis. With nothing else left to her, Elena goes to Logan and forms the Twin Pact with him, which binds their lives together.
