Also free @
B&N.
Given that it's a Dorchester book and
Dorchester have been notorious for selling authors' ebooks without having the rights and also not paying them royalties, then refusing to either pay or stop or both when called on it, I hope they actually have the rights to sell this one and compensate the author fairly.
Though I suppose they don't make actual money off offering this one for free unless someone goes and buys the rest, and the author does get a publicity boost, for better or worse.
