The Scoundrel and the Satyr King by Clio Evans

Dear Mister Ezra Fitzroy,

On account of the slanderous rumors revealing your ungentlemanly persona and the ill-gotten disgrace of the Fitzroy name, Her Majesty is compelled to deem the Season bequeathed to you a failure. Henceforth, in order to restore your and your family’s name, you are hereby ordered to attend the Monsters Ball by Her Majesty our Queen.
Ezra Fitzroy is a scoundrel. From the games he likes to play to the innocent wallflowers he likes to seduce— he is a devilish rogue with a hankering for trouble. After being kidnapped by his father and delivered to the ball, Ezra finds himself on his knees in a forced proposal to the Satyr King.
Pan is the charming and benevolent ruler of the creatures that live within the Lands of Essex, known to all as the Satyr King. Centuries of ruling these ancient lands have passed, and he finds himself with a conundrum— he must find a suitable mate, or he will have to give his crown to his bastard brother.
After a fateful encounter, Ezra and Pan are thrown into a game of royal charades. Our sunshiney Satyr has his work cut out for him if he wishes to seduce the scoundrel that no one has been able to love.
