EVERFALLEN (Based zeyn syre )

Christian Dean, England's most feared assassin, lives by a simple code: eliminate the target, leave no witnesses. But his latest mission plunges him into a hidden world of warring paranormal factions, where angels and demons clash in the shadows. To make matters worse, he finds himself irresistibly drawn to Nella Torre, his siblings' enigmatic teacher, unaware that she is a fallen angel battling her own demons.
When Zeyn and Micah stumble upon a string of mysterious disappearances-both human and paranormal children vanishing without a trace-Christian is forced to confront not only supernatural threats but also his growing feelings for a woman who could destroy him. As the lines between his past and present blur, Christian must choose between the life he's always known and a love that could redeem him. But with Nella's own dark secrets and the fate of innocent lives hanging in the balance, can they overcome the forces that threaten to tear them apart?
