I've read four new fantasy books. All of them were written quite well and I've only found one obvious case of self-copypasta (as in: an author pasted parts of a previously published work straight into his next). There may be a more detailed analysis to follow, but I'm not sure about that yet.
Unfortunately it seems like I'll have to wait a year for the next book from Diana Rowland to be published. At least if the information at shelfari is to be trusted as I've been to lazy to research further.
