** spoiler alert ** 
 The Jewel is about a girl named Violet Lasting. She is a surrogate which means she gives birth to royalty and rich merchants because the royals physically can't have strong, healthy babies. Violet is sold off and serves a Duchess. When she falls in love with a forbidden love, Violet is risking everything. 
 The Jewel had many issues that seemed to bother me. 
 1) She's a surrogate. That means Violet is sold off to royalty and rich merchants to have their kid. Violet is sold off to the Duchess of the Lake and, basically, is just thrown around like she's a doll. 
 2) Lucien is a lady-in-waiting. But he's a man. That's kinda weird. 
 3) Violet falls in love with Ash. This was actually my favorite part. I loved the romance between Violet and Ash. 
 4) Lucien gives Violet the serum, but she gives the serum away to Raven. That is incredibly nice and I love that part, too.
