This is an old series, but I just discovered it and could NOT put it down. It is an Arthurian historical-fantasy. The author is Gillian Bradshaw and the books are Hawk of May, Kingdom of Summer, and In Winter's Shadow. I just started a new one by her that I don't think is a series and it is called The Wolf Hunt. It's also historical fantasy about werewolves in medieval France. These books are SO delicious!
I've also been reading The ADHD Effect on Marriage, Is it You, Me, or Adult ADD, Living with Intensity, Perfect Targets (Asperger Syndrome and Bullying), The Unwritten Rules of Friendship.
But I'm going to have to go on Amazon and buy everything written by Gillian Bradshaw. I'm totally addicted to her right now.
