yes! omg thank you so much
it takes place in a historical setting and a prince from another country is tasked with protecting a political figure who people figure is old but it's actually him in the disguise and the person is actually who people thinks in the nephew of the said political figure. The prince doesn't really believe in religion but there is a pope who dissapproves and the queen is interested in him. That's about all i remember TT
