Reclaim Your Throne

In a world where magic is real, and kings rule over the land, a lone knight is sent out on a mission requested from another kingdom.

Retrieve the kingdom's runaway princesses, so that the oldest may be wed as soon as possible.
But when he finds this girl who is supposed to marry another, will he be able to let her go?

Not only that, but will he and the other kingdoms be able to take down the looming horror that threatens all of the land?

(An Alternate Universe with characters from the Naruto Series.
Book is set for those 18 and over, due to some graphical content, language, mentions of sexual activities, and more.
I do not own any characters from the Naruto series, only the characters I created myself, along with the exceptions of a few of my friends characters in the story.

This is also something I came up with myself, along with the help of @Itachi9695
I am not copying anyone else.)
