Short Version: At first read, a better read than the previous book, TSK: Legacy. Certainly not fraught with emotional danger for Dag & Fawn. Most of the time is spent with Fawn wowing everyone with her 133t cooking skilz and Dag wowing everyone with his 133t Lakewalker healing skilz. There isn't even that much sex in it. Mostly it's just a lazy trot down the river while Dag explores his emerging abilities.
I'm starting to think that the seperation between Lakewalkers and Farmers is more and more of a good idea. Dag moves from ground ripping a mosquito to an honest to Patrick Swayze spine removal by the end of the book. Never mind the bags full of oats sacrificed to his experimentation. Essentially he's doing Malice Magic for lack of a better term, and whatever Fawn's ideas about weapons aside, it's a useless skill against an aware and defensive Lakewalker (he got lucky with Crane) but devastating against a Ground blind Farmer. I suspect this, even more so than revealing Sharing Knife making secrets to Farmers, is going to bite Dag in the ass hard when his fellow Lakewalkers find out. Never mind the demands on other Lakewalker healers when word of his work reaches up the Grace River.
Because if it doesn't.... Well, Lois will finally have created a Gary Stu more obnoxious than our boy Miles Vorkosigan.
