Kate Daniels (book series)

Kate Daniels is an urban fantasy series written by the husband-wife duo Ilona Andrews. The first ten books were published under the Ace Books imprint of Penguin Random House between 2007 and 2018, with many appearing on the New York Times Best Seller list. The series has since been expanded upon in a number of self-published series, primarily from the point of view of supporting characters in the original ten books.

The series's heroine, Kate, is a gifted swordswoman who has been groomed from childhood to kill. She is unusual in her world, where magic has returned and alternates in apocalyptic waves with technology, in that she is able to survive on her own; however, through the series we see that she cares deeply about the people around her. Ultimately she would rather use her strength to protect them rather than to enshrine or - more likely - destroy herself.
