King's Cage by Victoria Aveyard

Book three in the Red Queen series. At the start of the this book Mare is a prisoner of Mavis having sacrificed herself to save the rest at the end of the second book. The captivity part seemed to drag on forever, and I found myself wishing ti was over already. Then the book finally started to get good, and it was over. Now I have to wait for the next one to find out what in the world happens next. Lots of good fantasy world building but slow on actual action events. I marked it as 4/5 stars on Goodreads but to be perfectly honest it is closer to a 3.5.
