The Glass Princess by Lidiya Foxglove

When I was a girl, my father forced me to swallow a magical crystal. The Dragon’s Tear turned my bones fragile as glass. I was no Ionger strong enough dance or learn to fight…or take any lover until my wedding day. I was destined to wed the King of the Dragons, and only he could restore my health.
Now it is time to fulfill the prophecy. To become King Aurekdel’s bride.

The dragon kingdom is an underground world of darkness and danger. When King Aurekdel was a baby, the kingdom was attacked by a traitorous mist dragon, and Aurekdel lost both his parents and his eyesight. The enemy still lurks, with an army of mist dragons and a new weapon: Ezeru, a mysterious dragon rumored to have god-like abilities to shape rock.
No…it certainly doesn’t sound like a place I want to be. Especially when I’m in love with the dashing young head of my guard, Oszin, who has been my best friend and secret crush since I was fifteen.
But Oszin can’t heal me. Only Aurekdel can. I already hate this blind king and his tall, fierce warrior champion Lord Seron. King Aurekdel is waiting for me…but on our wedding night, we won’t be alone.
I really had no idea what I was in for.

Aurekdel is charming and clever and he wants to give me everything I ever wanted and then some. The love of three protective men, a magical garden, a blessed sword, and the role of a great queen. But there is one thing he cannot give me. And to find the answer might threaten everything I hold dear…and gain the attention of the man who will change our destiny.
