His Beauty by Jack Harbon

An act of sacrifice and the consequences that follow.
When Isla’s father doesn’t return home on time, she’s certain something is wrong. A deft pickpocket his whole life, it’s unlike him to take so long on a run. It isn’t until her sister informs her of where he went that Isla understands just how much danger he’s put himself in.
Highburn Hold.
The castle no man or woman dare enter on their own. Ruled by a bloodthirsty abomination with a cruel streak and penchant for imprisonment. Finding her sickly father locked in one of the cells in Highburn’s dungeon, she knows in order to save him, she must offer the beast something else.
Something her father cannot.
Something the beast is hungry for.
