This is the third and final book of the Chosen King series and it takes place 6 months after the end of the 2nd book.
Without spoiling too much about the plot of book 2, things are sort of settling down in the Thirteen Kingdom and the majority of the citizens have accepted Gordon and Asa as their two teenage kings.

However, as one would expect, peace is ever elusive in this series, and the author cleverly manages to split the adventures of the book into two parts so as not to overburden the starring role of Gordon and Asa. While Gordon embarks on a diplomatic mission to a mysterious nation of social outcasts named the Outlands in order to discover the true reason behind the attack in his palace that injured Asa, his fellow co-king has to soothe an increasingly vociferous group of angered Thirteeners that wish to get rid of the teenager king system due to internal government problems that has weakened the country.

I like how the book manages to give the two kings an equal chance to shine and be strong in their own different ways, and while I personally think Cayne's character as an additional villain was weakened due to the fact that he was never introduced in book 2, the book continues to be entertaining with a satisfying ending. Overall, it was definitely a step up from book 2, and quite an entertaining kid friendly story.

PS: I do find it weird however that even though Aline knows how to make the bitter cakes that lower Gordon's blood sugar, the book forgets about this when he is running low on his medication. ( )
