His Hidden Heirs of the Blood Moon. The Forbidden Mate Chronicles, #2

She hid his heirs to save their lives. Now the Blood Moon has exposed them to the king she once fled. Eight years ago, Princess Elena Howard escaped the royal palace with her newborn twins after hearing her mate, Alpha King Daelen Flores, declare them dead-and discovering an order bearing his seal that demanded their sacrifice. To keep them alive, Elena made an impossible choice. She raised Luca in a remote mountain settlement and entrusted Harper to a powerful border witch, hiding both children from the royal bloodlines hunting them.
But when Luca's forbidden gift awakens beneath an early Blood Moon, every Alpha in the kingdom feels his power. Daelen discovers that the wife and children he mourned are alive. Elena discovers that the truth behind their disappearance may be far darker than the betrayal she believed. Luca can strengthen and heal wolves. Harper can strip away supernatural commands. Together, the secret twins threaten a monarchy built on stolen obedience-and expose a conspiracy that has sacrificed royal children for generations.
As rebellion spreads and a false prophecy demands Harper's death and Luca's coronation, Elena must return to the palace she escaped. To protect her children, she must uncover who forged the royal order, who deceived Daelen, and whether the powerful mate she once loved can become a father worthy of their trust. Daelen has one chance to prove that love is more than possession, protection is not control, and a family cannot be reclaimed by royal command.
But saving his children may require him to destroy the crown, surrender his inherited power, and become the one thing no Alpha King has ever been allowed to become-A man his family chooses freely. His Hidden Heirs of the Blood Moon is an emotionally intense paranormal fantasy romance featuring estranged fated mates, secret royal twins, a protective mother, a remorseful Alpha King, magical children, political betrayal, family reconciliation, and an earned happily ever after.
