The Daylight War by Peter V. Brett. Third book in the Demon Cycle series.
Amazing fantasy books. Extremely deep story and lore. Really enjoying the third installment, maybe not as much as the first and second books, but I still have 150 pages to go. Each main character has such an amazing back story and personality, extremely character driven with some amazing fight sequences with one of the mains becoming more powerful(think god like powers) by the page, though doesn't perfect or immortal. He has obvious flaws and is out numbered and out matched by antagonists of the series. Can't help but care about all the main characters, even if some of them are fuuuucked up.
Love this series.
