Paul Kearney is working on two new novels. The first is provisionally entitled The Other Side of Things and will be a sequel to his critically-acclaimed 2016 novel The Wolf in the Attic.
The Wolf in the Attic was an excellent novel, one of the top genre releases of 2016, and the news that we'll find out what happened next to Anna is most welcome. The Other Side of Things will likely be a 2019 release.
The other novel in the writing process is Calgar's Reckoning, a follow-up to Paul's Warhammer 40,000 novel Calgar's Siege. It's possible there will be even more novels from Paul in this setting, which is good news.
Unfortunately, it sounds like the copyright issues that led to his novel Umbra Sumus: Dark Hunters being put on indefinite hold are continuing. Don't hold your breath on seeing that in the near future.
