Barbara Hambly is pretty well known for her Benjamin January series, in which I've now read (and liked) a few books. And she also writes several science fiction series, which I haven't read and can't comment on. Now she has a new-ish mystery series out, the Silver Screen series, with only three books, at least so far. The first book is on sale right now for $2.99/£2.99 in the US/UK, and the second two books are "on sale" for around $5/£4, which I wouldn't have posted if not for the first book. The books are discountable at Kobo, and in a rare move, actually cheaper at Kobo UK than at Kindle UK, even without the discount...
