Caught sight of this via the interwebs: Desdaemona, by Ben Macallan (aka Chaz Brenchley). Released at the end of May. It’s got a nifty eye-catching cover; and an intriguing premise (Jordan sounds like a cool character, and people who have done Very Bad Things with immortals certainly promise much delightful mayhem). I haven’t read the book, but I’ve read some of Chaz’s stuff, and I have no doubt that this is going to be delightful and scary and full of awesome literary goodness–and very much NOT your average urban fantasy.
Plus, we definitely need more Brits trying out their hands at this sort of thing (I for one am getting tired of all those US settings and mindsets, and very much welcome stuff like Ben Aaronovitch’s Rivers of London/Midnight Riot, and Suzanne MacLeod’s Spellcrackers.com).

So, if you feel like checking it out, now’s the time… I’m off to preorder my own copy.
