Second Son (A Prequel to The Shattered Throne Series)
by Cate Dean
As the second son, Micah Brachon is happy to leave the responsibilities of running their small coastal kingdom to his brother. It allows more time for his inventions and experiments.
When one of those experiments is sabotaged, his ordinary life is turned upside down - and he finally learns about the deadly faction that seeks to rip apart the foundations of their government.
