Bones of Haven [EPUB ebook] 

There’s nothing safe about Haven, nor is there justice, truth, or honesty. The only thing stemming the forces of darkness from overtaking the city is the Guard, but even they are susceptible to bribes, threats, and general maliciousness. However, two members of the Guard hope to change that. Hawk and Fisher, the husband and wife team, are the only pure forces of good in Haven. They can’t be bought. They can’t stand for injustice. But they can kick your ass.Hawk and Fisher constantly find themselves in the middle of Haven’s trouble, but this time they might be in over their heads. A massive riot breaks out in the prison where all of Haven’s most notorious criminals – and wizards – and incarcerated, threatening the tentative Peace Talks the would bring peace to the kingdom. Their actions in the prison take them straight into the fold of Haven’s political battle where peace talks might meet a bloody end. As the action unfolds, Hawk and Fisher find themselves deeper and deeper in the conspiracy that ties the lowest of prisoners to the highest politicians in Haven. The toughest married couple faces their greatest (and perhaps final) battle in the stunning conclusion to the Hawk and Fisher series.
