Bigger and better. This is exactly the entry this series needed. The multiple POVs were used to great effect here. After enjoying this chunky read, I better understood the hype for the series. 

There is one plot hole that got me all fired up. At the end of book two the knights of archyron find Calen. They fight with him and help save him. He finds out one of them is Haim, thought to be dead. Their leader is slain so at the beginning of book three they just bounce. Calen even begs Haim to stay but they all leave. Not a single knight is left to keep the line open with Calen. Then later after the knights work out their situations they're all like... "we got to find Calen. It's important that we protect him." You were right there! You were protecting him! You left like the job was done.
