I recently recommended Flesh and Spirit by Carol Berg to someone on Twitter who said her favorite characters included Eugenides (The Thief), Miles (all the Miles books by Bujold) and Tremaine (The Fall of Ile-Rien books). I answered with Eugenides (The Thief), Ista (Paladin of Souls, also Bujold), Tremaine and Valen.
The more I think about it, the more it seemed Valen was an awful lot like Eugenides would have been if he hadn’t had a loving home life. They are both irrepressible, thieves and rascals. Of course, Valen is also a drug addict and a deserter.
