Just finished book 3, after putting off reading it because I couldn't clearly recall books 1 and 2 because it had been too long.  Now I NEED the 4th book! Is there any info or news of a 4th book?

Release dates for the series have been consistent, with one book published each year. Based on this pattern, we can expect the 4th book to be released in 2025. We're still awaiting an official announcement for the next book, so stay tuned!
