I recommend Eon. 
 ***** 
 This is a great story, but Eon (or Eona) being the heroine and the center of it all is just too painful for me. In short, i don't like her. If i was the dragon, i would find her unworthy of my powers. Despite my misgivings on the main character, the book is commendable for fantasy readers out there. 
 Eon is susceptible to emotional blackmail and manipulation. I agree that she is just a teenage girl living in a society where women do not hold power in any way, but her years in training should've given her nerves of steel, but it didn't. She isn't as strong and likeable as i thought she would be. I wanted to slap and strangle her most of the time i was reading her story. 
 The strongest character for me would be Ryko, followed by Lady Dela. I've underestimated their role due to their social ranking, but when i get past that, i was in awe of their courage and devotion to fight for what is right. 
 The storyline was built around palace intrigue and dragon lore. Unfortunately, it was focused more on the former rather than the latter which made half of my reading Eon boring and dragging. I was so looking forward to lots of DRAGON MAGIC! But there was only a few. I was elated during the choosing ceremony (ascending dragon will pick his worthy apprentice). Then I was dulled by the palace scenes. It only picked up during Eon's trial with the King Monsoon. And i was pysched that FINALLY, the author was in a roll. There is no time to put the book down after that. 
 The twist was a shocking realization for me. The scenes before arriving to that climax finally made sense to me, and it was thrilling! So simple yet clever on the author's part. 
 Only after closing the book did i say that i enjoyed Eon's story. I hope there's more of Prince Kygo in book two, though. Then i want to smack Dillon full in the face. 
 Eon inclined more on palace politics than the dragon fantasy it implied on the book cover and blurb. But i would still recommend it for the unique plot.
